The photodissociation of 1-bromopropane was investigated at 234 and 267 nm utilizing ion velocity imaging method. Both the speed and angular distributions of Br*((2)p(1/2)) and Br(P-2(3/2)) fragments were determined. ss(Br)= 0.77 +/- 0.07 and ss(Br*)= 1.68 +/- 0.06 at 234 nm; ss(Br)= 0.38 +/- 0.02 and ss(Br*)= 1.33 +/- 0.09 at 267 nm were observed. The total translational energy distributions were single Gaussian distribution and interpreted using soft or rigid implusive mode at different wavelength, respectively. The experiment also shows that Br is dominant in the dissociation and originates mostly from W, while Br* corresponds to 4A' <- 3A' coupling. (c) 2005 Elsevier B.V. All rights reserved.
