LOCAL MODE OSCILLATOR-STRENGTHS IN BENZENE

Experimentally, benzene C-H and C-D stretching modes are seen to behave as one dimensional oscillators with respect to both eigenenergies and oscillator strengths. Simple local mode models based on either Morse or quartic power series potential wavefunctions predict the correct behavior for the oscillator strength from the infrared to the visible red special region. However, it appears unlikely that the coefficients of the expanded dipole moment operator may be easily determined by a fit to the observed oscillators strengths of a Local Mode progression. © 1979 American Institute of Physics.
