Talk:HOMO and LUMO

subjacent frontier orbitals
The second highest occupied molecular orbital is known as "NHOMO" by IUPAC; it is referred to as "HOMO-1" or "H-1" in common usage. The second lowest unoccupied molecular orbital is defined as "SLUMO" by IUPAC. It is commonly labeled "LUMO+1", or "L+1"

SOMO
Shouldn't the title of this page be HOMO/LUMO/SOMO? The internal link SOMO links to this page, and I think this would be good for avoiding confusion. —Preceding unsigned comment added by 94.223.219.191 (talk) 12:44, 18 November 2009 (UTC)

Question
Is a SOMO considered a type of HOMO, or is it considered something different?

I suppose the question could also be phrased a different way: does a free radical have no HOMO? Stonemason89 (talk) 16:08, 4 June 2010 (UTC)
