Molecular Geometry and the Vapor Pressures of Isotopic Ethylenes: Chemical and Structural Isomers
Description:
The theory of isotope effects on vapor pressures for systems with large quantum effects, as manifested by the cross-over phenomenon and deviation from the rule of the mean, is illustrated by the large body of experimental data on the isotopic ethylenes which has recently become available. An effect of molecular geometry was found, viz. a difference in vapor pressures of cis-, trans- . and gemdideuteroethylenes. This was shown to be related to the hindered rotation about the C=C axis in the liqu…
