On the conformation of cyclohexane-1,4-dione and its derivatives-I : infrared and Raman spectra of cyclohexane 1,4-dione and infrared spectrum of its octadeutero analogue

Abstract

Raman spectra of cyclohexane 1,4-dione (I), in chloroform, benzene and water solutions have been recorded. Temperature effect on the spectrum has been studied. The IR spectra of I and its octadeutero analogue in the solid state have also been studied. The spectra have been found on the basis of selection rules applicable for Raman and IR spectra, to be consistent with a single conformer of C₂ symmetry. Plausible causes of conformational preference have been discussed.
