Ultraviolet photoabsorption in the B3S- - X3S- and C3p - X3S- band systems of SO sulphur isotopologues
Original language description
High-resolution far-ultraviolet broadband Fourier-transform photoabsorption spectra of (SO)-S-32-O-16, (SO)-S-33-O-16,(SO)-S-34-O-16, and (SO)-S-36-O-16 are recorded in a microwave discharge seeded with SO2. The B-3 sigma(-)(v = 4 30) <- X-3 sigma(-)-(v = 0) and C-3 pi (v = 0 7) <- X-3 sigma(-)-(v = 0) bands are observed or inferred in the 43,000-51,000 cm-1 (196 to 233 nm) spectral range. This is the first experimental detection of a C-3 pi(v > 2) level and of any of these observed bands in an S-substituted isotopologue. Additional measurements of A(3)pi(v = 1 3) <- X-3 sigma(-)(v = 0) provide a calibration of the SO column density. Measured band profiles are fitted to an effective-Hamiltonian model of coupled excited B-3 sigma(-)- and C-3 pi states along with their predissociation linewidths and absorption band strengths. Electronic-state potential-energy curves and transition moments are deduced. The end result isa list of line fre-quencies, f-values, and dissociation widths describing the far-ultraviolet photodissociation spectrum of SO that is accurate enough for computing atmospheric photolytic isotope-fractionation. Linelists, and photoabsorption and photodissociation cross sections are available as supplementary data.
