Mathematical Interpretation of Rao’s Rule and Its Application to Spherical and Non-Spherical Molecules

抄録

The utility of Rao’s rule has been extended to spherical and non-spherical molecules of some of the gases at their liquefaction temperature on the basis of interaction potential. The necessary equation for Rao’s constant has been derived in terms of potential parameters and the formula for the velocity of sound in different gases at their liquefaction temperature has been suggested. The present approach is simple and adequate keeping in view the approximation involved in the theory.
