| Abstract: | R band (26.5–40 GHz) microwave spectra have been recorded for the common isotopic species of 6-endo-methylbicyclo3.1.0]hexan-3-one and 6-exo-methylbicyclo3.1.0]hexan-3-one. These spectra are shown to be consistent with a ground vibrational state boat conformation having five membered ring dihedral angles of 7.2 ± 0.3° and 20.5 ± 1.4° respectively. This information is correlated with product quantum yields obtained on photolysis of these molecules. |
