Vibrational analysis of 1-chlorononane

Abstract

Fourier transform infrared and Raman spectra of the organic compound 1-chlorononane have been recorded in its liquid state at ambient temperature in the ranges 4000-400 cm^-1 and 3200-150 cm^-1, respectively. A detailed vibrational analysis in terms of assignment of the observed vibrational bands of 1-chlorononane has been done to different modes of vibrations for its four most probable conformations with symmetries <i>C_s</i> and <i>C₁</i> in its liquid phase with the aid of normal co-ordinate calculations. The normal co-ordinate calculations have been carried out utilizing the computer program MOLVIB. The potential energy distribution has also been calculated for each mode of vibration.
