At this stage of your education, you should be consulting more than one text to enhance your learning and understanding of the material. No particular book is perfect in all respects and scientists regularly refer to several books and papers to understand a concept.
“Atoms, Molecules, and Photons: An Introduction to Atomic, Molecular, and Quantum Physics”, by W. Demtröder. Springer 2006. An electronic copy of this book is available through the UofG library
Links to lectures, office hours, and assignments will be posted on Courselink.
“The Fundamentals of Atomic and Molecular Physics”, by R.L. Brooks, Springer 2013.
“Introduction to the Physics of Matter: Basic atomic, molecular, and solid-state physics”, by N. Manini, Springer 2014.
“Introduction to Quantum Mechanics” by D.J. Griffiths. Cambridge University Press, 2018.
Teaching and Learning Activities
Topics for PHYS*4120:
Part 1: Atoms
• Quantum structure of atoms. Atomic spectra. Bohr’s atomic model. Some spectroscopic notations.
• One electron atom/ions: Energy spectrum. Angular and radial wavefunctions. Orbital angular momentum and magnetic dipole moment. Addition of angular momentum. Electron spin. Fine structure. Nuclear spin and Hyperfine structure. Electronic transitions and selections rules. Spectra in magnetic field.
• Many-electron atom: Identical particles. Pauli principle. Anti-symmetrisation. Independent particle approximation. The two-electron atom. The Hartree-Fock method. Electronic structure. Spectroscopy: core levels, optical spectra, electric-dipole selection rules.
Part 2: Molecules
• The adiabatic separation.
• Chemical and non-chemical bonding: H2+. Covalent and Ionic bonding. Weak non-chemical bonds. Classification of bonding.
• Intermolecular dynamics and spectra: Rotational and rovibrational spectra, electronic excitations. Zero-point effects.
Marking Schemes & Distributions
Method of Evaluation:
The midterm test is tentatively scheduled for Wednesday, October 20, 2022 from 10:00 am-11:20 am, in-class.
Assignments (5-6) will be due approximately every two weeks, on the date of the deadline (no late assignments accepted unless prior arrangements have been made). Some questions will require computation (using python). High presentation standards are expected (legible handwriting, commented code, etc.)
There will be 8-10 quizzes, given on a ~weekly basis. Each will have about 5-10 multiple choice or short answer questions which will test the material covered in the lectures and assignment work. The quizzes will be online.
Collaboration versus Copying
Scientists work alone or in groups, very often consulting fellow scientists and discussing their research problems with peers. Collaboration is a feature of scientific activity, and there are many benefits to working with others. However, no ethical scientist would ever publish or claim the work of others as their own, and scientists give reference to the appropriate source of ideas or techniques which are not their own.
You are a young scientist, and, in this spirit, I encourage you to discuss with others as you learn the material and work on the problem assignments. However, the work that you submit as your assignment must be your own and not a copy of someone else’s work. Identical scripts will be given a mark of zero and plagiarism will be dealt with severely. I encourage you to cite your references, citing books and other articles when they are used and acknowledging discussions with those who have helped you in your understanding and completion of the problem. This is good scientific practice.
Course Evaluation Information
The Department of Physics requires student assessment of all courses taught by the Department. These assessments provide essential feedback to faculty on their teaching by identifying both strengths and areas of improvement. In addition, the annual student assessment of teaching includes part of the information used by the Department Tenure and Promotion Committee in evaluating the faculty member's contribution to teaching. The Department's teaching evaluation questionnaire invites student response through numerically quantifiable data and written student comments. In conformity with the University of Guelph Faculty Policy, the Department Tenure and Promotions Committee only considers comments signed by students. Your instructor will see all signed and unsigned comments after the final grades are submitted. Written student comments may also be used in support of a nomination for internal and external teaching awards.
NOTE: No information will be passed on to the instructor until after the final grades have been submitted.
Please note that the ongoing COVID-19 pandemic may necessitate a revision of the format of course offerings and academic schedules. Any such changes will be announced via CourseLink and/or class email. All University-wide decisions will be posted on the COVID-19 website and circulated by email.
The University will not normally require verification of illness (doctor's notes) for fall 2020 or winter 2021 semester courses. However, requests for Academic Consideration may still require medical documentation as appropriate.
As per university regulations, all students are required to check their e-mail account regularly: e-mail is the official route of communication between the University and its students.
When You Cannot Meet a Course Requirement
When you find yourself unable to meet an in-course requirement because of illness or compassionate reasons please advise the course instructor (or designated person, such as a teaching assistant) in writing, with your name, id#, and e-mail contact. The grounds for Academic Consideration are detailed in the Undergraduate and Graduate Calendars.
Students will have until the last day of classes to drop courses without academic penalty. The deadline to drop two-semester courses will be the last day of classes in the second semester. This applies to all students (undergraduate, graduate and diploma) except for Doctor of Veterinary Medicine and Associate Diploma in Veterinary Technology (conventional and alternative delivery) students. The regulations and procedures for course registration are available in their respective Academic Calendars. Undergraduate Calendar - Dropping Courses
Copies of Out-of-class Assignments
Keep paper and/or other reliable back-up copies of all out-of-class assignments: you may be asked to resubmit work at any time.
The University promotes the full participation of students who experience disabilities in their academic programs. To that end, the provision of academic accommodation is a shared responsibility between the University and the student. When accommodations are needed, the student is required to first register with Student Accessibility Services (SAS). Documentation to substantiate the existence of a disability is required; however, interim accommodations may be possible while that process is underway. Accommodations are available for both permanent and temporary disabilities. It should be noted that common illnesses such as a cold or the flu do not constitute a disability. Use of the SAS Exam Centre requires students to book their exams at least 7 days in advance and not later than the 40th Class Day.
The University of Guelph is committed to upholding the highest standards of academic integrity, and it is the responsibility of all members of the University community-faculty, staff, and students-to be aware of what constitutes academic misconduct and to do as much as possible to prevent academic offences from occurring. University of Guelph students have the responsibility of abiding by the University's policy on academic misconduct regardless of their location of study; faculty, staff, and students have the responsibility of supporting an environment that encourages academic integrity. Students need to remain aware that instructors have access to and the right to use electronic and other means of detection. Please note: Whether or not a student intended to commit academic misconduct is not relevant for a finding of guilt. Hurried or careless submission of assignments does not excuse students from responsibility for verifying the academic integrity of their work before submitting it. Students who are in any doubt as to whether an action on their part could be construed as an academic offence should consult with a faculty member or faculty advisor.

Recording of Materials
Presentations that are made in relation to course work - including lectures - cannot be recorded or copied without the permission of the presenter, whether the instructor, a student, or guest lecturer. Material recorded with permission is restricted to use for that course unless further permission is granted.
