CHEMISTRY AND CHEMICAL ENGINEERING 177<br />
Ch. 156 a, b. INTRODUCTION TO WAVE MECHANICS, wrrH CHEMICAL<br />
ApPLICATIONS. 6 units; first and second terms.<br />
After a discussion <strong>of</strong> the development and significance <strong>of</strong> the new<br />
quantum mechanics, the wave equation <strong>of</strong> Schrodinger is used in the<br />
treatment <strong>of</strong> the oscillator, rotator, and hydrogen atom. The perturbation<br />
theory and the theory <strong>of</strong> the Heisenberg-Dirac resonance phenomenon<br />
are then developed and applied to various problems, including the<br />
Stark effect, helium atom, hydrogen molecule ion, hydrogen molecule,<br />
forces in the hydrogen halides, Van del' 'Wanls' forces in helium, the<br />
scattering <strong>of</strong> X-rays by bound electrons, and the sharpd electron pair<br />
bond.<br />
(Not given in 1929-1930.)<br />
Instructor: Pauling.<br />
Ch. 157. THE STRUCTURE OF CRYSTALS. 6 units; third term.<br />
The' subject treats the methods <strong>of</strong> determining the structures <strong>of</strong><br />
crystals with X-rays; the various structures occurring in nature, and<br />
their relation to the phenomena <strong>of</strong> isomorphism, solid solution formation,<br />
cleavage, etc.; ionic and atomic sizes and their bearing on the chemical<br />
properties <strong>of</strong> substances; interatomic forces in crystals; the crystal<br />
energy and its use in chemical thermodynamics, and related topics.<br />
(Not given in ] 9529-1930.)<br />
Instrudor: Pauling.<br />
Ch. 158. PHOTOCHEMISTRY. 6 units; first term.<br />
Lectures and discussions on photochemical processes, especially in<br />
their relations to quantum phenomena. The following topics will bc<br />
included: the photochemical absorption law; the processes-excitation,<br />
dissociation, ionization-accompanying the absorption <strong>of</strong> radiation; subsequent<br />
processes including fluorescence and collisions <strong>of</strong> the second<br />
kind; photosensitization; quantum yield and its relation to photochemical<br />
mechanism; catalysis and inhibition; temperature coefficients <strong>of</strong> photochemical<br />
reactions.<br />
(Not given in 1929-1930.)<br />
Instructor: Dickinson.<br />

Ch. 160. INORGANIC CHEMISTRY (Seminar). .6 anita! seeond tanH. '! '<br />
Selected groups <strong>of</strong> inorganic compounds (e.g., the various compounds<br />
<strong>of</strong> nitrogen with hydrogen and with oxygen) will be considered from<br />
modern physico-chemical view-points; thus with reference to their physical<br />
properties, their thermodynamic constants (their heat-contents, freeenergies,<br />
and entropies); their rates <strong>of</strong> conversion into one another<br />
(including effects <strong>of</strong> catalysis and energy radiations), the ionization <strong>of</strong>
