“…Delocalization of lone pair orbitals by methyl substitution has been reported with EMS on NH 3 − and H 2 O. − In the present study, alkyl substituent effects on sulfur nonbonding orbitals are studied with EMS. Experimental momentum profiles (XMPs) of the highest occupied molecular orbitals (HOMOs) of H 2 S, C 2 H 5 SH, n -C 3 H 7 SH, i -C 3 H 7 SH, and (CH 3 ) 2 S have been measured and compared with theoretical momentum profiles (TMPs).…”

Electron Momentum Spectroscopy Study of Lone Pair Orbitals of Thiols and Dimethyl Sulfide

1997

Experimental momentum profiles of the lone pair orbitals of several thiols and dimethyl sulfide have been measured and compared with theoretical momentum profiles. All the observed profiles exhibit p-type character, confirming that the orbitals have been characterized as sulfur nonbonding orbitals. However, small shifts in the profiles are found, depending on substituents. The results are discussed in relation to the geometries of the molecules.
