Tune-resolred expenments are reported showing kinetic evidence for vibrational relaxation of electronically excited mokcules in solution at room temperature. The experiments mvolve higher electronic states of 3,4,9,10~iibenzpyrene. Data are consistent with slow vibrational relaxation (== 15 ps), sim

โฆ Synopsis
Vibrational frequencies in excited and ionized states are ca.IcuIated for primary aromatic hydrocarbons, on the basis of MO cdcuhtions of transition energies and normal coordhate ulculations for ground state moIecuIes. Results are in good agreement with experiment-Specific activities of certain types of modes, which exhibit Iarge frequency shifts on excitation. are discussed in terms of vibronic coupJim&

The dynamic nature of the quenching of the fluorescence of 1,4\_amino-and hydroxy-substituted 9, IO-anthraquinone, with benzene, alkylbenzenes and other aryl hydrocarbons as quenchers, indicates formation of exciplexes, where charge transfer (CT) occurs from the S, (quencher) to the S, (fluoropliore
The energies of the zero levels of the iower excited states of the mono-negative ions of naphthalene and biphenyi and the mono-and di-negative ions of anthracene, tetracene and pentacene were determined by a closer inspection of the lower frequency regions of their optical spectra.

Quenching of aromatic excited singlet states (9,10-dimethyl anthracene, 9,10-diphenyl anthracene and perylene) by nitroxyl radical was studied by flash photolysis and fluorimetrically. It is established that the dominant quenching mechanism is enhanced intersystem crossing in the collision complex w
