Pyrene quenching in a fluorescence, photoacoustic, and two-photon photoionization cell
Journal Article
·
· Spectrosc. Lett.; (United States)
A nitrogen laser-excited windowless flow cell has been used to examine the effects of various quenching agents (CH/sub 3/NO/sub 2/, CCl/sub 4/, and CH/sub 3/CH/sub 2/I) on the fluorescence (FL), photoacoustic effect (PA), and two-photon photoionization (2PI) of pyrene in ethanol. The results show that both the lowest excited singlet state (S/sub 1/) and the lowest triplet (T/sub 0/) are involved as real intermediate states in the consecutive two-photon photoionization of pyrene.
