Abstract
This paper describes how optical spectroscopic constants can be used to calculate the speed of sound as a function of temperature in diatomic gases. A general expression for the speed of sound is derived by using the vibrational partition function of the gas. The presented method was evaluated for oxygen and nitrogen. The results are in good agreement with the measured data.
