In the past year, our specific aims were to study excited (singlet)-state dynamics of heteraromatic molecules related to proximity effect, spin-sublevel dynamics of the lowest triplet state of diazanaphthalenes and methyl substituted pyrazines, and radiationless transitions in electron donor-acceptor complexes (exciplexes and charge-transfer complexes). In addition to successfully completing several aspects of these objectives, we have carried out pico-second spectral studies of temperature dependence of fluorescence and triplet formation in fluid solutions of acridine, which does not exhibit photophysical properties of molecules with nearby n..pi..* and ..pi pi..* singlet states. The progress on each is discussed.
