Two photon dissociation of acetone, acetaldehyde, and acetic acid at 243 nm: Translational energy releases in the H atom channel

초록

The hydrogen atom channels from photodissociation of acetone, acetaldehyde, and acetic acid at 243nm have been investigated by detecting H atoms using two photon absorption at 243.2nm and induced fluorescence at 121.6nm. Translational energies of the H atoms were measured by Doppler broadened H atom spectra. By absorption of two photons at 243nm, the H atoms were produced from acetyl radicals. The possible dissociation mechanisms are discussed from the measured translational energy releases. © 2001 Elsevier Science B.V.
