✦ Synopsis
Ultraviolet photoelectron spectra of the disulfoxides of 2,6-dithiaspiro [3.3.] heptane,2,8-dithiaspiro[3.1.3.1.] decane, and 2,10-dithiaspiro t3.1.1.3.1.1.1 tridecane show that there are substantial through-bond interactions of the sulfur lone-pairs, ranging from 0.85 eV for the compound with two rings to 0.25 eV for the compound with four rings. Through-bond interactions of orbital=' can have significant chemical consequences. A recent review, dealing with this issue2 , noted that interactions between basis orbitals separated by up to six bonds have been observed. "The possibility of an electron or positive hole being transmitted through-bonds over large distances within a molecule is intriguing." (quote from ref.2).
