Abstract

Tables are presented for the contribution of a harmonic oscillator to the free energy function, enthalpy function, entropy, and heat capacity of gases. Dimensionless values of the Planck-Einstein functions are given as a function of x = hcv/kT for x = 0.0010(.0001) 0.1500(.001) 4.000(.01) 10.00 (.2)16.0. A second table which gives the contributions in cal/mole º K directly as a function of frequency v, and temperature T, was computed using the values 1.43880 for the second radiation constant hc/k, and 1.98717 for the universal gas constant R. The arguments for the latter table are spaced at 10 wave number intervals from 100 cm l to 4000 cm 1 .
