Abstract

Part of the low temperature calorimetric research program of this laboratory has been the careful detennination of the entropy of simple compounds in which hindered rotation about single bonds would be expected and for which straightforward and reliable statistical mechanical calculations can be made. Of the compounds available, ethane and similar molecules with two symmetrical groups on a common axis seem best suited for study both because of their convenient boiling points and because their configurations and normal frequencies can be readily determined. The existence of a barrier of about 3000 cal/mole hindering internal rotation in ethane was established by Kemp and Pitzer and Kistiakowsky, Lacher and Stitt.
