Abstract
A highly influential paper by DOUGLAS [1] in 1966 called attention to the fact that reported lifetimes for certain states of CS2, NO2 and SO2 were significantly longer than predicted from absorption measurements of oscillator strengths. He proposed that interactions with nearby states having little or no radiative transition probabilities resulted in mixed levels with lengthened lifetimes. Since that time the use of lasers to excite fluorescence from these molecules has revealed features more complex and interesting than previously suspected. The two principal findings are: 1) the fluor-esence decays are multiexponential showing short as well as long-lived components; 2) the frequency resolved spectra reveal both discrete and continuous features.

The level density due to the ground state calculates to be 1 cm using the formula of P. C. Haarhoff, Mol. Phys. 7, 101 (1963). R. M. Hochstrasser has called our attention to the possibility that this value may significantly underestimate the true density since the formula does not account for anharmonicities.
