Abstract

The far-infrared spectra of 3-methylenecyclohexene, 4-methylenecyclohexene, and 1-methyl- 3-methylenecyclohexene in the region of 80-400 cm-1 are reported and interpreted mainly with a view to the two lowest out-of-plane deformations of the cyclohexene ring. Typical C- type band sequences are observed and interpreted in terms of ring inversion modes. Barriers to inversion are determined by means of a one-dimensional Hamiltonian with a ...
