“…The SO molecule is isovalent with O 2 with an X 3 − ground state and low-lying metastable a 1 and b 1 + states. The strong B 3 − -X 3 − UV transition [8] is analogous to the Schumann-Runge system of O 2 . The forbidden b 1 + -X 3 − and a 1 -X 3 − transitions have been measured in the near infrared region at 955 nm and 1.7 µm, respectively [ 9 , 10 ].…”

“…25 The use of two distinct input frequencies for TC-RFWM provides an added benefit since the signal is obtained only when both frequencies interact with distinct molecular transitions that share a common level. 18 These examples show convincingly that the selection of the spectroscopic method is subtle and that a combination of different (linear and nonlinear) techniques is often beneficial for a detailed spectroscopic analysis. 4,30 The selectivity of the two-color technique by intermediate level labeling is advantageous for the simplification of spectrally congested regions.…”

A new apparatus is described that uses nonlinear and linear spectroscopic techniques simultaneously for the characterization of stable and transient molecules in a molecular beam environment. Short-lived species are generated by applying a well-defined discharge on a suitable precursor prior to supersonic expansion. Femtosecond ionization and mass spectrometry is used to optimize the discharge source. Degenerate and two-color resonant four-wave mixing spectroscopy (DFWM and TC-RFWM, respectively) are used in tandem with laser-induced fluorescence (LIF) and cavity ring-down spectroscopy (CRD). We demonstrate initial experiments on the 4051Å band of C 3 (Ã 1 5 u −X 1 6 + g , 000-000). DFWM, LIF and CRD display similarities in the general shape and position of the rovibronic transitions. A more detailed view, however, reveals the complementary character of the methods and the potential of simultaneously measured spectra. High signal-to-noise ratios and well-structured spectra are obtained by DFWM. LIF is favorable for the observation of weak features but strongly dependent on the relaxation mechanism of the upper excited state. CRD suffers generally from a large background signal but yields quantitative information. By applying the methods in parallel, quantitative measurements of molecular number densities, transitions dipole moments and relaxation rates are accessible.

In a new study on sulfur monoxide, new ab initio potential energy curves are developed for excited states A3Π, B3Σ–, C3Π, and C′3Π and for three states that are unassigned in the literature, which we numerically name 33Σ–, 43Π, and 53Π. All these excited states have allowed transitions from ground state, X3Σ–. The ab initio calculations were performed using the MRCI-F12+Q/aug-cc-pV(5+d)Z level of theory implemented in MOLPRO2015. On the basis of close-coupling R-matrix theory, fine structure absorption cross sections of isotopically substituted sulfur monoxide are calculated for wavelengths of 190–300 nm. The spectra are shown at the highest possible resolution (FWHH ≈ 0.15–0.18 cm–1) for reference and future studies. The effects of self-shielding and possible mutual shielding are discussed.
