✦ Synopsis

The effect of rotational excitation on the clcctionic relaxation of the S1 state of "isolated" benzene,h+s been studied by examination of resonance fluorescence generated when narrow-band exciting light is swept through the rotational env-elop cf four S1 *So absorption bands. To within the ten perent uncertainty in measurement, the fluorescence yields are independent of the position of the exciting Light within an absorption band. Thus neither radiative decay nor intersyste,m crossins to the triplet state displays Luge sensitivity to moIecuIar rotation, at least when excited state relaxation proceeds from rotational disMbutions of moderate diversity.
