Vibrational spectra of 2-cyclohexen-1-one and its 2,6,6-d3 isotopomer

The infrared and Raman spectra of 2-cyclohexen-1-one and its 2,6,6-d3 isotopomer in their liquid and vapor phases have been recorded and a complete vibrational assignment was carried out. DFT theoretical calculations were carried out to predict the vibrational frequencies and the agreement is excellent.
