Notes
o | Energy separation between the v = 0 levels of the excited and electronic ground states. |
x | Energy separation between the band maximum of the excited electronic state and the v = 0 level of the ground state. |
t | Energy separation between the v = 0 levels of the two excited states involed in the transition. |
