Abstract
The low‐frequency (100–500 cm−1) infrared and Raman spectra of bicyclo [3.2.0] hept‐6‐ene and its 2‐oxa analog have been analyzed. The large collection of transitions involving the four out‐of‐plane ring modes were assigned and complex interaction was found. For the oxa compound a detailed energy level diagram was determined from the 30 transitions observed. Analysis of the ring‐puckering spectra demonstrated that the asymmetric potential energy functions had only one energy minimum within 4 kcal/mole of the ground state, which corresponds to a boat species. Whether a second minimum is present at higher energies could not be determined.
