CALIFORNIA INSTITUTE OF TECHNOLOGY
theory of apace groups and the use of symmetry in the determination of the structures
of crystals. The detailed study of representative .tructure investigations. The
various known crystal structures and their rdation to the physical and chemical
properties of substances. The quantitative treatment of X-ray diffraction. Fourierseries
methods of structure investigation.
It is planned that this subject be given in 1940-1941, and every third year
thereafter.
Instructors: Sturdivant, Pauling.
Ch. 228 a, b, c. Crystal Structure Laboratory. Units determined by the
instructor; any term.
Practical instruction is given in the methods of determining the .tructure of
crystals with X-rays.
Instructor: Sturdivant.
Ch. 229. Diffraction Methods of Determining the Structure of Molecules.
6 units.
A discussion of the diffraction of X-rays and electrons by gases, liquids, glasses,
and crystals.
Instructors: Sturdivant, Schomaker, Hughes.
Ch. 230. Photochemistry. 6 unit.; third term.
Lectures and discussions on photochemical processes, especially in their relations
to quantum phenomena. The following topics will be included: the photochemical
absorption law; the processes-excitation, dissociation, ionization-accompanying
the absorption of radiation; subsequent processes including fluorescence and collisions
of the second kind; photosensitization; quantum yield and its relation to photochemical
mechanism; catalysis and inhibition; temperature coefficients of photochemical
reactions.
Instructor: Dickinson.
Ch. 232. Radioactivity and Isotope .. 6 nnits; third term.
Lectures and discussions on natural and artificial radioactivity. The fundamental
particles and isotopes. The applications of natural and artificial radioactive ,ub­
.cances and isotopes to the study of chemical and biochemical reactions are discussed.
Instructors: Dickinson and Yost.
Ch. 234. Introdllction to the Spectra of Molecules. 6 units; first term.
The theory of the structure of the spectra of both the diatomic and the simpler
polyatomic molecules is presented, and the transition rules and their relation to the
symmetry elements of molecules are discussed. Emphasis is laid on the methods of
interpreting and analyzing molecular spectra, and it is shown how from an analysis
one obtains information regarding the structure and other properties of a molecule
of interest to the chemist. Problems are given in the interpretation of actual data.
Instructor: Badger.
Ch. 243. Quantitative Organic Microanalysis. 20 units (0-20-0); any
term by arrangement.
Laboratory practice in the methods of quantitative organic microanalysis required
for structure determinations of organic compounds. Students must obtain
permission from the instructor before registering for this subject as the enrollment
is necessarily limited.
Instructor: Haagen-Smit.
