High - Resolution Spectroscopy of Jet - Cooled SO 2 and SO 2 : The ã 3 B 1 – X̃ 1 A 1 , 20 1 and 10 1 Bands
نویسندگان
چکیده
Laser-induced excitation spectra of the two bands ã B 1–X̃ A 1, 2 0 1 and 10 1 of SO2 and SO2 have been recorded in a supersonic jet at a resolution of 0.015 cm. The rotational and electron-spin fine structure has been analyzed for both isotopic species. Analysis of the rotational and electron-spin fine structure yields precise values of the rotational constants A, B, and C and the spin constants a and b for both SO2 and SO2 in the states ã B 1 (010) and (100). No interaction between these two vibrational states with any nearby triplet state is observed for rotational levels with J # 8 and K # 2. © 2000 Academic Press Key Word: sulfur dioxide.

The electronic spectrum of a cold molecular beam of zirconium dioxide, ZrO(2), has been investigated using laser induced fluorescence (LIF) in the region from 17,000 cm(-1) to 18,800 cm(-1) and by mass-resolved resonance enhanced multi-photon ionization (REMPI) spectroscopy from 17,000 cm(-1)-21,000 cm(-1). The LIF and REMPI spectra are assigned to progressions in the Ã(1)B(2)(ν(1), ν(2), ν(3))...

High-resolution laser excitation spectroscopy has been used to record the à E-X̃ A1 electronic transition of SrCH3 in a laser ablation/molecular jet source. Transitions arising from the K =1 ←K =0, K =0←K =1, and K =2←K =1 subbands have been observed and assigned. The data were modeled with E and A1 symmetric top Hamiltonian matrices in a Hund’s case a basis, using a least squares fitting progra...
