Vibrational modes of CH bonds in n-paraffin molecular chains: an algebraic description

Abstract

We apply the one-dimensional vibron model to compute energies and infrared intensities of CH vibrational modes (stretching and bending states) of n-paraffin molecules. We consider the possible onset of interactions between different kinds of bending motions as well as that of anharmonic resonances between CH stretching modes and CH bending overtone/combination vibrations.
