Notes

1Single progression consisting of seven bands 3; vibrational numbering uncertain.
2Observed in the flash photolysis of SeCl2. The assignment of this spectrum to SeCl is not certain. It is assumed that only one component of 2Pi - 2Pi is observed because of large doublet splitting in the lower state.
3The first and last bands of the progression are diffuse.
