VIBRATIONAL SPECTRA OF METHYL 2, 2-DIMETHYL -3-KETOCYCLOBUTYL ACETATE (I) AND METHYL 2,2-DIMETHYL-3-HYDROXYCYCLOBUTYL ACETATE (II)

The Raman and the infared spectra of methyl 2, 2-dimethyl 3-ketocyclobutyl acetate and methyl 2, 2-dimethyl-3-hydroxy- cyclobulyl acetate have been studied and the observed frequencies have been analysed in terms of characteristic group frequencies. The keto ester (l) shows two frequencies in the carbonyl stretching frequency region while the hydroxy ester (II) shows only one. A comparison has been made with the available data for cyclobulane compounds and the possible characteristic frequencies for these compounds are discussed.
