| Resumo | |
The B2Sigma+ electronic state, and the X2Pi-B2 Sigma+ and A2Sigma+-B2Sigma+ transitions of the SiP molecule were characterized theoretically at a high-level of correlation treatment. Potential energy curves, dipole and transition moments, radiative transition probabilities, and radiative lifetimes are reported. Emission from the B state is presented as a possibility to spectroscopically characterize the ground state and the first excited A2Sigma+ state with a Te value of just 470 cm-1. These transitions are predicted to lie in the blue region of the visible spectrum. SiP excited in the B state should have a radiative lifetime of 1.0 us. (AU) | |
