Abstract

Photodissociation dynamics of CF3Br has been investigated at 225 nm, where the 3Q0 state is accessed exclusively. It has been revealed that the ground state Br(2P3/2) is hardly formed with a relative quantum yield less than 5%. The recoil anisotropy of Br*(2P1/2) has been found to have a limiting value, βBr* = 1.90 ± 0.05. The total translational energy distribution for the Br* channel was well fitted by a Gaussian function with an average of 155 kJ/mol and a width of 30 kJ/mol. It has been proposed that the 3Q0 state is not bent and the dissociation on this surface proceeds in a collinear geometry.
