Learning outcomes
The students learn: to master their mathematical knowledge in order to apply it to problems in Physical Chemistry; the fundamentals of molecular symmetry and of quantum mechanics for following studies in atomic and molecular structure;to apply the methods of quantum mechanicsfor studying the electronic properties, especially the energy levels,of atoms and simple molecules.

Teaching methods
The course is organized in three learning modules: Mathematical Methods for Chemistry (5 credits) and Atomic and Molecular Structure (4 credits) with its additional module of laboratory work (1 credit). Classes of the first module are given in the first semester; classes of the second and third modules are given in the second semester.
Classes are organized as lectures in the classroom, in-class exercises and, for the third module only, laboratory exercises.
All students must attend Module 1, 2 on Health and Safety, online.
Assessment methods
Learning assessment is evaluated only by means of the final examination. This aims at verifying the student's knowledge and skills by means of one test for each semester.
For the first module there is first a written examination with exercises, which lasts 3 hours. A minimum grade of 16/30 is required for the admission to the oral exam, where, after a discussion of the written test, two questions concerning the course contents are asked to the student.
For the second and third modules, there will be a written test where the student will have to solve one numerical problem, followed by a viva examination relative to the course contents and the laboratory activity.
The final grade is the arithmetic mean of the grades obtained for each learning module.
Teaching tools
