The fluorescence spectrum of 7-hydroxycoumarme m ethanol excited by a pulsed tunable dye laser reveals different features when excitation proceeds via one-photon and two-photon absorption. In the former case the spectrum shows two peaks delayed in time by approximately 2 ns and characterized by diff

## Abstract The determination of reactionβrate constants of unimolecular, pseudoβunimolecular and bimolecular reactions by means of absorption spectroscopy is described. The calculation of immeasurable absorption spectra by this method is given.
The transtent absorption behaviour of lOHacndtn-g-one and the Iktlkyi-subaituted derivattves has been investigated wtth a nanosecond dye-laser spectrometer. The S, -S, and Tt -T, absorptjons were compared m soluhons of ethanol, cyclohexane and PMMA, with and without time delay of the spectroscopic b
