β¦ Synopsis
Intramolecular heteroeuxmer formation processes in the excited state of p(CHs)*N-C6H1~CH*)3-(9anthryi) (As) as well as p_(CH3)2N-C6Hq-(CH2)3-(l_pyrenyl) (P3) in hexane and l-propa~~ol have been investigated by meansoF picosecond time-resolved fluorescence measurements.

Time development in the nanosecond range of the intramolecular excimer fluorescence of 1.3dinaphthylpropane is studied using a single-photon counting technique. The rate constants for the association and dissociation process are obtained at different viscosities. The radiative lifetime of the excime
## Abstract Preliminary experiments using PerotβFabry interferometers demonstrated the possibility of filtering selectively the fluorescence background from Rayleigh scattering excited by 25 ps pulses. Experiments aimed at extending the technique to spontaneous, Raman scattering are in progress. Th
Picosecond time-resolved fluorescence spectra of all-trans retinal in hexane have been measured with 8 ps time-resolution with use of a highly sensitive streak camera. The observed fluorescence consists of a fast (r < 1 ps, ,h.ma x m 470 nm) and a slow (r = 33-34 ps, Ama x --540 nm) component. The l
