“…Few experimental spectroscopic data are available for the a 1 Δ 2 state. The experimental T e (T 0 ) and ω e (in terms of ΔG 1/2 ) values for this spin-orbit state, reported by Setzer and coworkers [17], are 749 cm −1 smaller and about 15 cm −1 larger, respectively, compared to that computed in the present study.…”

“…There are several experimental spectroscopic studies [9][10][11][12][13][14][15][16][17] available for this molecule. Clark and Scaife [9] have reported the fundamental vibrational frequencies (ω e ) of all the homonuclear and heteronuclear diatomic molecules containing atoms of group VIA.…”

“…Fink and co-workers [16] have studied the b0 + -X 1 0 + and b0 + -X 2 1 subsystems of the b 1 Σ + -X 3 Σemission system of SeS with a Fourier transform spectrometer and reported some molecular constants for the b0 + , X 1 0 + and X 2 1 states. Setzer and co-workers [17] have studied the emission spectra of SeS in the near-infrared spectral region and reinvestigated the b 1 Σ + (b0 + )-X 3 Σ -(X 1 0 + , X 2 1) transitions. In addition, they have observed the a 1 Δ(a2)-X 3 Σ -(X 1 0 + , X 2 1) transitions of SeS for the first time and reported some spectroscopic constants such as T e , B 0 and ΔG 1/2 for the a 1 Δ(a2) state.…”

The electronic states and spectroscopic properties of selenium monosulfide (78Se32S) have been studied using relativistic configuration interaction methodology that includes effective core potentials of the constituent atoms. Potential energy curves of several spin-excluded (Λ−S) electronic states have been constructed and spectroscopic constants of low-lying bound Λ−S states within 5.1 eV are reported in the first stage of the calculations. In the next stage, the spin–orbit interaction has been incorporated and its effects on the potential energy curves and spectroscopic properties of the species have been investigated in detail. After the inclusion of spin–orbit coupling, the is identified as the spin–orbit (Ω) ground state of the species. The transition moments of several important dipole-allowed and spin-forbidden transitions are calculated and the radiative lifetimes of the excited states involved in the respective transitions are computed. Electric dipole moments (μz) for some low-lying bound Λ−S states as well as a few low-lying spin–orbit states (Ω-states) are also calculated in the present study.

“…In optical spectra, parallel electric and magnetic dipole lines previously have been observed only in the spin-forbidden b 1 R + ? X 3 R À transitions of SO [38], SeS [39,40] and SbH [41]. Pure magnetic dipole bands have been found in the X 2 1 g ?…”

a b s t r a c tEmission spectra of bismuth monohydride (BiH) radicals excited by energy transfer from O 2 (a 1 D g ) or NF(a 1 D) or by a DC discharge in a mixture of bismuth vapor and hydrogen in a fast-flow system were studied in the wavenumber range from 4000 to 25 000 cm À1 with a Fourier-transform spectrometer.The X 2 1 ? X 1 0 + transition between the spin components of the X 3 R À ground state was remeasured at high spectral resolution and signal/noise. Six bands of the Dv = 0 and +1 sequences near 4950 and 6600 cm À1 have been observed. The low-J lines of these bands are split into up to 10 hfs components due to magnetic hyperfine structure splitting of the X 2 1 levels. In addition to the previously observed electric dipole lines, weak magnetic dipole lines show up in the Dv = 0 but not in the Dv = +1 bands. The intensities of the Dv = +1 bands are about a factor of 10 higher than expected from FranckCondon factors indicating that the electric dipole transition moment l X2-X1 shows a strong dependence on internuclear distance. Near 5450 cm À1 , the 0-0 and 1-1 bands of the transition a2 ? X 2 1 from the hitherto unknown first excited state a 1 D(a2) to the upper component of the ground state have been observed. The lines in these bands show the magnetic hfs splitting of both the a2 and X 2 1 states. In the visible range near 21 300 and 16 300 cm À1 , the 0-0 and 1-1 bands of the b0 + ? X 1 0 + system and the 0-0 band of the b0 + ? X 2 1 transition likewise have been measured at high resolution. The lines of the latter band also show the hfs splitting of the X 2 1 state. Least-squares fits have yielded rotational and vibrational constants of the X 1 0 + , X 2 1, a2, and b0 + states as well as hfs parameters of the X 2 1 and a2 states and the electronic energy of the hitherto unknown a 1 D(a2) level.
