IMAGING PHOTOFRAGMENTS IN VELOCITY SPACE BY LASER SHEET ILLUMINATION TECHNIQUES - PHOTODISSOCIATION OF ICN

Combining laser sheet illumination and two-dimensional imaging techniq ues, photofragmentation of ICN at 248 nm was studied in detail. The th ree-dimensional distribution of number density, angle and velocity of state-selected CN photofragments was successfully determined by slicin g an expanding, spherical shell from the photodissociation center sequ entially. Studies of photodissociation processes and elementary chemic al reactions by these experimental techniques are expected to provide new insights into their dynamic properties, as evidenced in the presen t experiment on photofragmentation of ICN.
