Content
The chief purpose of the course is to teach some elementary theory, with major emphasis on the interpretation of infrared spectra. The problem sessions will consist of the interpretation of previously prepared spectra. Topics to be covered include: introductory theory of molecular vibrations and absorption of infrared radiation; origin of group frequencies and interaction and coupling effects; techniques used in obtaining infrared spectra; methods of making band assignments through selection rules, gas contours, and isotope effects; and interpretation of IR spectra of numerous organic compounds.
The course presents an introduction to the analysis and interpretation of electron spin resonance spectra. A Varian E3 spectrometer will be used to take spectra of many samples, including solids. The effects of variation of experimental parameters and hyperfine splitting (by single nucleus, by a set of equivalent nuclei, and by nonequivalent nuclei) are explained and demonstrated with many spectra. These spectra are taken from free radicals in solution, aliphatic radicals, and defects in solids. Examples are worked out to obtain expressions for g-value components. Manipulation of spin operators is explained, assuming no previous experience.
For whom
The course will be of most value to organic chemists who have made some preliminary use of IR spectroscopy as a tool for the study of molecular structure. However, no previous IR experience is required.
This course is designed for advanced undergraduates, graduate students, college teachers, industrial chemists, and other chemists who have had no previous introduction to ESR.

There is no deadline for registration—applications are accepted as long as there is room in each session, including the period after the cancellation deadline. Early enrollment is strongly encouraged, however, both to allow sufficient time for precourse study and to ensure registration since the enrollments are limited. ACS Short Courses are open to all—it is not necessary to be a member of the local section or an ACS member. A person requiring employer authorization should enroll without payment. However, if he then does not receive authorization, he must cancel before the cancellation deadline or else be personally responsible for payment of the fee. A limited number of student registrations at one half the regular fee will be available in each course. Each student application must be accompanied by a letter from a faculty member, on the department letterhead, stating that the registrant is a full-time student.
