β¦ Synopsis
Multiphoton krser-induced decomposition is reported here for photolysis of ketene with 9.260 pm radiation from a pulsed CO2 TEA laser. Chemical end products of this photolysis were primanly Ha and CO. Visible chemihtminescence, attributed to Ca Swan band emission, wns observed during the fust = 1 ps folIowin,o photolysis. A collision-assisted dissociation, fol-Ioned by rcphotolysis of the transient products, is proposed to account for the results.

Both the primary and resulting yields of the multiphoton dlssonabon (MPD) of (CF&CI upon CO&scr irradiation are found to depend strongly on the CO+ser radiation frequency. The consecutive multiphoton frwmenration of (CF~JC radicals produced in the MPD of (CF3)&1 is shown to occur at several laser fr
bstract -Absorption spectra of poly(N-vinyl-{arbazole) and related polymers in the excited singlet, triplet, cationic, and anionic states were measured by nanosecond and picosecond laser photolysis methods and compared with those of model bichromophoric compounds.

The photochemistry of ketene adsorbed on Pt( 111) has been studied by illuminating the adsorbate-metal system with UV photons (2 in the range 300-420 nm) and detecting changes in the chemisorbed layer as reflected in the subsequent thermal desorption and SIMS spectra. The photon-induced changes were
## Abstract The decomposition of cyclobutyl chloride following multiple infraredphoton excitation has been investigated. The primary photolysis products are butadiene, from elimination of HCl, and ethylene and vinyl chloride, fromring scission. The vinyl chloride undergoes secondary decomposition t
