Abstract

Photodissociation of cyanogen halides, ClCN, BrCN and ICN, was investigated using synchrotron radiation. The absolute cross-sections for the photoabsorption and the production of CN(B²Σ⁺-X ²Σ⁺) emission were determined in the wavelength range of 50-180 nm (200,000-55,000 cm^-1). The observed photoabsorption spectra displayed congested structures, indicating the presence of a number of Rydberg states in the energy region under the second ionization potential. No structures were observed beyond the second ionization potential. The quantum yield for the CN(B²Σ⁺) production first increased with excitation energy and then suddenly decreased at the excitation wavelength corresponding to the opening of the ionization channel.
