The triplet-triplet electronic excitation transfer from benzophenone IO naphthalene in rigid solutions has been investigated by measuring the non-exponential decay curve of benzophenone phosphorescence using a laser pulse for excitation. The results of measurements were satisfactorily reproduced by

β¦ Synopsis
Due to a significant discrepancy between theoretical calculations and euperimcntal exit&on data, the position of the low-lying triplet state df water has been much debated in recent years. WC now report that the corresponding transition (= 4.0 eV) can be observed also in emission upon charge neutralization in r-irradiated ordinary and heavy ices and also by photosensitization fram the mercury 3PI or 3Po state. The observed radiative decay is cha:acterized by an emission X,, at 380-385 nm.

of.reIative quantum yields of pkosphorescene have been made for naphthalene versus perdeuteranaphthalenc and for toluene versus perdeutcrotoluene, all contained in argon crystds at 20Β°K. In combination with tripIet lifetime measurements these quantum yield ratios give the ratios of radiative tripfet
The structures and properties of the ground and low-lying excited states of Li2H have been investigated by ab initio calculation. The UMP2-0ptimized geometry of ground-state Li2H is in agreement with experiment. Properties of the excited 2B2 and 2A 2 states have been predicted, based on UMP2-0ptimiz
Ab initio cakulatiuns using the restricted Roothaan open-shell method indicate that the energy separation between the rawest two triplet states of formamide, and their conforma~on~ preferences, depend significantly upon the @~metry of the molecule.
