A rew method for obtaining picosecond infrared spectra and kinetics is presented. It incorporates a tunable infrared diode laser in conjunction with two cavity-dumped dye lasers synchronously pumped by a mode-locked and Q-switched Nd:YAG laser. New results are obtained for the photodissociation of h

β¦ Synopsis
We show that the open period of a CS2 light gate, triggered by a picosecond optical pulse, depends on the optical pathlength through the CS2. An alternative to the light gate is suggested for time resolved spectroscopy. The working principle is based on scattering induced in CS2_ We have found that the broadband emission from Hz0 or D20 excited by a 5300 A picosecond pulse is also of picosecond duration, bxt the blue part is delayed with respect to the red. From this delay time the lifetime of the ground state vibrational levels may be measured directly.

Stimulated Raman scattering (SRS) in compressed hydrogen and methane gas was characterized in terms of pulse energy, temporal width and spectral width in the range of gas pressures 10-60 atm to use it as a light source for picosecond time-resolved resonance Raman spectroscopy. SRS was pumped by the

The largcs~ gain ever reponed (1.1 X103 cm-') was obtained by a DEANS (0.7 mol dm-") doped polymer film. The S, -\* S,, gain of DEANS (1.2x lo-' mol dm -3) in benzene decreases wi
This paper mainly deals with the identi"cation of structural modal parameters, from output accelerometers only, using a vector autoregressive moving average (VARMA (p, q)) model method. The problem of determining the order p of the AR part, or equivalently the number of modes in a frequency band, is
