โœฆ Synopsis


Resonance fluorescence characterized by anomalously long radiative lifetime was observed from the skcond excited singlet state of the "isolated" 3.4 benzpyrene molecule, confkmiag theoretical predictions for strong ROR adiabatic coupling between two close lying electronic states of a large molecule. This communication is concerned with the features of the radiative decay of the second excited singlet state, $;, of la.+, isolated (collision free) aromatic

FIuorescence quenching of some polycyclic hydrocarbons in different solvents has been studied as a function of excitation wavelength. With most quenchers the Stern-Vobner quenching constant remafns fnsensitive to the wavelength of the irradiating beam. But when CC14 and CHCi3 are used as quenchers.
