Abstract

A number of low- J lines of the C Σ4 - →X Σ4 - (0,0) band of a supersonic molecular beam sample of vanadium monosulfide (VS) have been recorded at a resolution of approximately 50 MHz by laser excitation spectroscopy. The electric field induced shift and splitting have been analyzed to give the permanent electric dipole moments μ of the C Σ4 - (υ=0) and X Σ4 - (υ=0) states as 2.38(13) and 5.16(5) D, respectively. An electrostatic model is used to predict μ for VS and VO. A molecular orbital correlation diagram is used to rationalize the trends in experimentally observed μ values of the 3d -monosulfides and 3d -monoxides. A comparison with theoretical predictions is made.
