Abstract

Measured fluorescence lifetimes of individual rovibronic levels in SiH₂(Ã¹B₁,0n0), n = 1-3 and 6-10, vary irregularly from one level to the next. The distribution of these fluctuations about their average value is well fitted by the procedure of maximal entropy without additional constraints. This suggests that the intramolecular evolution at that energy range (ca. 18 000-24 000 cm^-1) is chaotic and uniformly samples its available phase space.
