Fine-structure branching ratios and Doppler profiles of Cl(2Pj) photofragments from photodissociation of the chlorine molecule near and in the ultraviolet region

Article abstract of DOI:10.1063/1.463285

Photofragment chlorine atoms in the ²P_j states from Cl2 at 266-500 nm are measured by a resonance-enhanced multiphoton ionization technique.The measured branching ratio of *(²P_1/2)>/2P_3/2)> increases monotonically with dissociation wavelengths from (9.5 +/- 1.8) * 10^-3 at 308 nm to (4.7 +/- 0.5) * 10^-1 at 475 nm.At 375 nm<*>λ<*>475 nm, Doppler profiles of the chlorine atoms indicate adiabatic formation of two Cl(²P_3/2) from the ¹Π(1_u) state of Cl2 and Cl(²P_3/2) + Cl^*(²P_1/2) from the B ³Π(0_u⁺) state.On the other hand, at a shorter wavelength (308 nm), Cl^*(²P_1/2) is generated from the ¹Π(1_u) state through nonadiabatic transitions during the dissociation.The relative contribution of the ¹Π(1_u) <- X ¹Σ(0_g⁺) and B ³Π(0_u⁺) <- X ¹Σ(0_g⁺) transitions in the photoabsorption is estimated from the obtained branching ratios at 375 nm<*>λ<*>475 nm.
