Of these, those followed most closely are: a Survival Facts from Quantum Mechanics b Perturbation Theory and Subgroups c Antisymmetric Wavefunctions: Slater Determinants The course provides a shortened Introduction to the fundamentals and applications of the theory of Group representations in Chemistry.

The content of the course will be narrowed compared with our current Chem to accommodate a later development of modular format of Chem The student will be encouraged to develop both the formal skills of using Group theory to grind out answers and to acquire some intuitive and pictorial sense of what it all means. For the more mathematical formal first third of the course, the lectures will probably more closely follow the text than the second half. For many topics, particularly with aspects of quantum mechanics and those dealing with solids, additional handouts and reference materials are necessary and available.

The anticipated point breakdown should go as follows: 5 problem sets normalized to 30 pts each , one midterm exam pts , and a final exam pts. Students are expected to make a serious attempt at every assigned homework problem before consulting with peers, otherwise collaboration is permitted as long as significant contributions are made by all collaborators.

Do not expect to be able to do all problems in a problem set in a single sitting. Module 1 required of all students 10 lectures I.

## Group Theory: Theory

The symmetry relationships in the molecular structure provide the basis for a mathematical theory, called group theory. The mathematics of group theory is predominantly algebra. A symmetry element is a geometrical entity such as a point, a line or a plane about which an inversion a rotation or a reflection is carried out in order to obtain an equivalent orientation. A symmetry operation is a movement such as an inversion about a point, a rotation about a line or a reflection about a plane in order to get an equivalent orientation. The various symmetry elements and symmetry operations are listed in below table. A point in the molecule from which lines drawn to opposite directions will meet similar points at exactly same distance.

Molecular symmetry in chemistry describes the symmetry present in molecules and the classification of molecules according to their symmetry. Molecular symmetry is a fundamental concept in chemistry, as it can be used to predict or explain many of a molecule's chemical properties , such as its dipole moment and its allowed spectroscopic transitions. To do this it is necessary to classify the states of the molecule using the irreducible representations from the character table of the symmetry group of the molecule. Many university level textbooks on physical chemistry , quantum chemistry , spectroscopy and inorganic chemistry devote a chapter to symmetry. The framework for the study of molecular symmetry is provided by group theory , and in particular irreducible representation theory.

### Group Theory: Theory

Group Theory is the mathematical application of symmetry to an object to obtain knowledge of its physical properties. What group theory brings to the table, is how the symmetry of a molecule is related to its physical properties and provides a quick simple method to determine the relevant physical information of the molecule. The symmetry of a molecule provides you with the information of what energy levels the orbitals will be, what the orbitals symmetries are, what transitions can occur between energy levels, even bond order to name a few can be found, all without rigorous calculations. The fact that so many important physical aspects can be derived from symmetry is a very profound statement and this is what makes group theory so powerful. To a fully understand the math behind group theory one needs to take a look at the theory portion of the Group Theory topic or refer to one of the reference text listed at the bottom of the page. Never the less as Chemist the object in question we are examining is usually a molecule.

Милый, я… я сейчас задохнусь! - Ей стало дурно. Все ее внутренности сдавило этой немыслимой тяжестью. - Despiertate! - Ее пальцы инстинктивно вцепились ему в волосы. Просыпайся.

Идиот! - в сердцах воскликнула. - Ты только посмотри. Сквозь строй дважды отверг этот файл. Линейная мутация. И все-таки он пошел в обход. Интересно, о чем он. У Бринкерхоффа подогнулись колени.
