Relativistic calculations on the transition electric dipole moments and radiative lifetimes of the spin-forbidden transitions in the antimony hydride molecule
文献摘要：
Calculations on the spectroscopic constants and transition properties of the first three states(a1 △,b1Σ+,and X3Σ-)of the SbH molecule were performed under the relativistic framework using the exact two-component Hamiltonian(X2C).The potential energy curves in the Franck-Condon region were computed and compared with the previous values.Fur-thermore,the transition dipole moments for the weak spin-forbidden transitions(b0+-X10+,b0+-X21,X10+-X21,and X21-a2)were reported.The spontaneous radiative lifetime of the b1∑+(υ′=0)state was calculated as 163.5±7.5 μs,which is in reasonable agreement with the latest experimental value of 173±3 μs.The spontaneous radiative life-times of the X21(υ′=0)state and the a2(υ′=0)state were calculated to be 48.6 s and～8 ms,respectively.Our study is expected to be a benchmark transition property computation for comparison with other theoretical and exper-imental results.The datasets presented in this paper,including the transition dipole moments,are openly available at .
