Infrared intensities of CCl stretching vibrations in cis- and trans-4-t-butylcyclohexyl chloride

Abstract

Infrared intensity measurements of cis and trans isomers of 4-t-butylcyclohexyl chloride in CS₂ solution show that the apparent molecular extinction coefficient for the equatorial CCl stretching vibration is 60 percent greater than the value for the axial CCl stretching vibration. The integrated absorption intensity is 47 percent greater for the trans isomer. Dilute solutions of the individual isomers conformed to Beer's Law. No solute—solute interaction was observed for solutions of isomeric mixtures.
