Theoretical investigation of potential energy curves and radiative lifetimes of low-lying electronic states in GeH+ radical cation

- The excited states of GeH+ were calculated with MRCI + Q method.
- The spin-orbit coupling effect was taken into account in the calculations.
- Spectroscopic constants of bound Λ-S and Ω states of GeH+ were computed.
- The radiative lifetimes of A1Π1, a3Π0+, and a3Π1 states of GeH+ were obtained.
