摘要: Potential energy and dipole moment functions for the ground states of SH, SH+, SH− have been calculated from highly correlated electronic wave functions. The electric moments in vibrational 32SH, 32SH+, 32SH− are to be 0.74, 1.29, 0.27 D, rotationless rates spontaneous emission A10 1, 52, 75 s−1, respectively. predicted transition probabilities between low lying state SH SD among smallest so far known allowed rotation‐vibration transitions. A–X confirm recent indirect determinations radiative lifetimes absorption oscillator strengths predissociating v’=0 level A state. 4Σ− is intersect A 2Σ+ at R=3.1 a.u., classical turning points 1
