The lower excited states of CS: A study of extensive spin-orbit perturbations

Transition Probabilities in theA1Π–X1Σ+System of CS

“…7. This improvement is due to better spectroscopic constants, as of the vibrational population is in £Љ Å 0, and the rotational distribution populates levels up to JЉ Ç 40 with a maximum Bergeman and Cossart forecasted (13), and more accurate experimental I £ £ Љ . However, two points, those for the 1,2 near JЉ Å 15.…”

“…The main difficulty in a systematic study of this transition is the high The CS radical has been observed as a product in both degree of perturbation of many A state rotational levels by the ultraviolet photolysis and the collisional dissociation, via nearby triplet states, leading to anomalies in line positions, metastable rare gas atoms, of the parent molecules CS 2 , intensities, and lifetimes (8,(10)(11)(12)(13). Hynes and Brophy (8) OCS, and CSCl 2 (1)(2)(3).…”

“…The experimental results are analyzed using RKR Information on features related to intensities within the curves constructed with spectroscopic constants from a deperturbation study (13). These improvements lead to a R e (r) 1 results, within experimental error.…”

VIS and VUV spectroscopy of 12C17O and deperturbation analysis of the A1Π, υ = 1–5 levels

“…The assignment of perturber levels, the selection of which parameters and interactions could be discriminated from our spectra, and the values of these parameters were iteratively optimised. The Pgopher program 67 uses the effective Hamiltonian with matrix elements similar to Field, 30 Bergeman et al, 84 and Le Floch et al 31 The model is presented in The unweighted obs-calc residuals of the tting method are dominated by the uncertainties of the very weak and heavily perturbed lines that belong to the weakest B-A (1, 1) and (1,5) bands. The weighted contribution to the root-mean-square (rms) residual value of high-accuracy dispersive optical spectroscopy and VUV-FTS data is 0.006 cm…”

Elastic and absorption cross sections for electron–carbon monosulfide collisions

“…In the present study, the average excitation energy is taken as the arithmetic average of the experimental values of the first ionization potential [23] and the electronic excitation threshold [24] of CS. The Lippmann-Schwinger (LS) scattering equation is solved using the SVIM.…”
