Vibrational spectroscopy of C_m–H, C<i>_β</i>–C<i>_β</i>stretching vibrations of Nickel metalloporphyrins: An algebraic approach

Abstract

Abstract An algebraic model of coupled anharmonic oscillators is introduced, capable of describing the stretching vibrations of medium and large polyatomic molecules. This model is applied to the calculation of Cm–H and C β –C β vibrational modes of nickel octaethyl porphyrins and nickel porphyrins molecules. The model appears to describe the data accurately.
