THE MICROWAVE SPECTRUM OF METHYL VINYL ETHER,
Abstract
Many of the lines in the microwave spectrum of methyl vinyl ether were assigned to a planar cis molecular conformation, having the following principal moments of inertia, Ia = 27.7382, Ib = 79.1268, and Ic = 103.678 gm sq. cm2. The dipole moment of the cis structure was measured and found to be 0.98 = 0.02 D (mu-a = 0.30 D and mu-b = 0.93 D). Vibrationally excited states of this species were assigned using a microwave double-resonance technique. This method consists of observing the change in one transition while a second transition is saturated with microwave power. Changes occur only if the two transitions have a common energy level. Various evidence indicates an unusually large value for the barrier to internal rotation of the CH3 group. (Author)
