Notes:
Intramolecular vibrational energy redistribution (IVR) is treated. Nearly isoenergetic rigid-rotor harmonic-oscillator states are rovibronically coupled by the interplay of anharmonic and Coriolis forces. The theory predicts linewidth distributions of rovibronic states and explains the selective supression of rotational spectral lines. Applications to sub-Doppler spectra of the 1410120 band of benzene allow to extract values for effective intramolecular interactions. These results are supported by direct calculations based on the force field.
