In this question enter subscripts and superscripts as normal text (e. g.. 4B2u would be entered as 482u). What is the symmetry of the HOMO in methylene? What is the molecular term symbol for the ground state electronic configuration of methylene? The first two excited states for methylene arise from promotion of an electron from its HOMO to its LUMO. The term symbol for the lowest energy and the term symbol for the higher energy state is state is
