THE MICROWAVE SPECTRUM, BARRIER TO INTERNAL ROTATION, AND QUADRUPOLE COUPLING CONSTANTS OF TRANS 1-CHLOROPROPYLENE,

Abstract

The microwave spectra of two isotopic species of trans chloropropylene, CH3CH=CHCl-35 and CH3CH=CHCl-37, have been measured and assigned. The quadrupole coupling constants of the Cl-35 nucleus were determined from the hyperfine structure. A few transitions were further split by the linear effect of the barrier to internal rotation of the methyl group. From these separations the barrier height was measured to be 2170 ! 100 cal/mole.
