An ab initio study of the structure and vibrational spectrum of allene
oxide and three of its isotopomers has been carried out (MP2/6-31G).
A comparison of the computed spectra with the experimental spectra re
ported previously (K.A. Singmaster and G.C. Pimentel, J. Mol. Struct.,
194 (1989) 215) confirms the assignment of four bands attributed to a
llene oxide.
