Notes

oEnergy separation between the v = 0 levels of the excited and electronic ground states.
xEnergy separation between the band maximum of the excited electronic state and the v = 0 level of the ground state.
aSeparation of band origin for an excited state of H3 or D3 from the lowest bound state, 2s 2A1'.
