First determination of isotopically invariant parameters of the negative ion—Hydrogen sulfide anion (SH −)

The first isotopically invariant Dunham analysis of a negative ion (the hydrogen sulfide anion SH −) that uses all available infrared and sub-millimeter wave experimental data on 32SH −, 33SH −, 34SH −, and 32SD − yields accurate information on Born–Oppenheimer breakdown parameters. The potential co...

Description
Summary:The first isotopically invariant Dunham analysis of a negative ion (the hydrogen sulfide anion SH −) that uses all available infrared and sub-millimeter wave experimental data on 32SH −, 33SH −, 34SH −, and 32SD − yields accurate information on Born–Oppenheimer breakdown parameters. The potential constants of expansion of the potential function up to the sixth order were calculated. Differences between the construction of the potential function based on the Morse potential and that on the base of the power series expansion are shown.
