MICROWAVE SPECTRUM, QUADRUPOLE COUPLING CONSTANTS AND BARRIER TO INTERNAL ROTATION OF 2-IODOPROPENE

Abstract

R- and Q-branch transitions of 2- iodoproene have been analyzed between 8 and GHz for the ground vibrational state. Rotational constants, centrifugal distortion constants and quadrupole coupling constants have been determined. In addition, several vibrationally excited states have been identified. From the splittings in the first torsionally excited state, the barrier to internal rotation of the methyl top has been determined.""
