Photodissociation of allyl cyanide at 193 nm

Photodissociation dynamics of allyl cyanide at 193 nm has been investigated by measuring laser-induced fluorescence spectra of CN fragments. From the spectra, rotational and vibrational energy distributions of CN have been ob tained. The measured average rotational energy is 1080, 900 and 760 cm(-1) for v" = 0, 1,2, respectively, and the fraction of the vibrational populati on is 0.70/0.24/0.06 for v" = 0/1/2. The measured distributions are well re presented by statistical prior calculations, from which the detailed dissoc iation dynamics is discussed. (C) 2001 Elsevier Science B.V. All rights res erved.
