Simple Computer Programming in the Physical Chemistry Course A rather simple program for the calculation of 18 arid 2s Slater atomic orbital functions for the ground state of carbon has been developed far use by students in the physical chemistry course. ANDHEW, JK., "MolecPlots of such orbital functions w e available in the literature [STKISITWP:ISEH, ular Orbital Theory for Organic Chemists," John Wiley & Sons Ioc., New York, 19611. I t is rewarding for the student to write or to use such a program, insert his own iuput values, then to plot the results and compare them with diagrams found in the literat,ure. Punching his own data cards for the computer input gives the student practical keypunching experience. This also should provide some motivstion for literature searches for formulae for other atoms, as well as exposure to Slilter's Rules and to other orbital functional farms [KAUZMANN, WILTI;K, Quantum Chemistry," Academic Presr, Inc., New York, 1957; COWLSON, C. A., "Valence," OxfordUniversity Press, Inc., New York, 1952; 19611. The development of other simple computer programs suitable for physical chemistry is planned far the future. A listing of the program, written in FOItTItAN IY for an IBM 1130 machine, is available from the author. The author gratefully acknowledges assistance from the Tufts University Computer Center. . I .
