The Hyperfine Structures of ScCl and ScF

“…Clearly all the values are comparable, thus implying with this model that the p-and d-orbital populations are essentially the same. It is generally accepted (29,33) that the valence molecular orbitals of all three compounds are approximately: (17), and (ii) for eQq 0 : the ratio of the nuclear quadrupole moments (18). The uncertainties in these values are three to four orders of magnitude smaller than the least significant digit given in this table.…”

A study of the A2Π–X2Σ+ and B2Σ+–X2Σ+ band systems of scandium monosulfide, ScS, using Fourier transform emission spectroscopy and laser excitation spectroscopy

“…A modified version of the laser ablation/supersonic expansion production scheme used in the previous ScS study [7] was selected for sample preparation. A variable speed rotating Sc metal rod was irradiated by the third harmonic (355 nm) light originating from a Q-switched Nd:YAG laser operating at approximately 1 mJ/pulse and at 20 Hz.…”

“…The (v = 1) B 2 R + state in [7] was erroneously referred to as the (v = 0) B 2 R + state. A prerequisite for the analysis of the optical Stark spectra was the recording and analysis of the field-free low-N lines of the B 2 R + -X 2 R + (1, 0) band.…”

“…Only lines having N 00 6 3 were included in the analysis. A review of the spectroscopy can be found in [7].…”

“…Recently the permanent electric dipole moments of the (v = 1) B 2 R + and (v = 0) X 2 R + states were determined from the analysis of the molecular beam optical Stark laser excitation spectra [also called laser induced fluorescence (LIF)] for numerous lines of the B 2 R + -X 2 R + (1, 0) band [7]. The (v = 1) B 2 R + state in [7] was erroneously referred to as the (v = 0) B 2 R + state.…”
