โฆ Synopsis
Ihe surface of the lowest excited smgkt state in meth;lne IS analyzed usmg a basis yet composed of 4-3 IC; augmented by a set of one s and three p Rydbergs. The State (IT2 in Td syrnnrctry. 1 Li, In C 2v! is fmnd to bc dissociatlvc to I B I Cllz and ground state &. Vcrtirally a llydbcrg state, 1B1 rapidly becomes a valence state on dtQortions from tetrahedral syW mctry. Avoided cros\mgs with higher B, SI.I~C~ arc diccusqcd.
