Photodissociation of isobutene at 193 nm.
The collisionless photodissociation dynamics of isobutene (i-C(4)H(8)) at 193 nm via photofragment translational spectroscopy are reported. Two major photodissociation channels were identified: H + C(4)H(7) and CH(3) + CH(3)CCH(2). Translational energy distributions indicate that both channels result from statistical decay on the ground state surface. Although the CH(3) loss channel lies 13 kca...
متن کاملPhotodissociation of propargyl chloride at 193 nm.
The photodissociation of propargyl chloride (C3H3Cl) has been studied at 193 nm. Ion imaging experiments with state-selective detection of the Cl atoms and single-photon ionization of the C3H3 radicals were performed, along with measurements of the Cl + C3H3 and HCl + C3H2 recoil kinetic energy distributions, using a scattering apparatus with electron bombardment ionization detection to resolve...
متن کاملPhotodissociation dynamics of ClN3 at 193 nm.
Photofragment translational spectroscopy was used to identify the primary and secondary reaction pathways in 193 nm photodissociation of chlorine azide (ClN(3)) under collision-free conditions. Both the molecular elimination (NCl+N(2)) and the radical bond rupture channel (Cl+N(3)) were investigated and compared with earlier results at 248 nm. The radical channel strongly dominates, just as at ...
متن کاملDiscrimination of product isomers in the photodissociation of propyne and allene at 193 nm
The photodissociation dynamics of propyne and allene are investigated in two molecular beam/ photodissociation instruments, one using electron impact ionization and the other using tunable vacuum ultraviolet ~VUV! light to photoionize the photoproducts. The primary dissociation channels for both reactants are C3H31H and C3H21H2. Measurement of the photoionization efficiency curves on the VUV in...
متن کامل193-nm photodissociation of acryloyl chloride to probe the unimolecular dissociation of CH2CHCO radicals and CH2CCO.
The work presented here uses photofragment translational spectroscopy to investigate the primary and secondary dissociation channels of acryloyl chloride (CH2==CHCOCl) excited at 193 nm. Three primary channels were observed. Two C-Cl fission channels occur, one producing fragments with high kinetic recoil energies and the other producing fragments with low translational energies. These channels...
