A Valence Force Field for Furan and Pyrrole and Their Deuterium and Methyl Derivatives.
J Molecular Spectroscopy 1971 Jan; 37(1):77-91
A molecular vibrational analysis was carried out for furan and pyrrole and their deuterium and methyl derivatives to establish vibrational assignments for use in statistical thermodynamic calculations. To insure convergence in the least-squares adjustment of force constants, interaction constants were assumed transferable between the furan and pyrrole rings, and observed wave-numbers of the two compounds and their derivatives were used in a single adjustment.
