Photoelectron radical cations, intramolecular

A short remark on tri- and polythia compounds Several such substrates (1,3.5-trithiane, 1,4,7-trithiacyclononane, 1,4,7,10-tetrathiacyclodecane, and 1,5,8,12-tetrathiacyclotetradecane) have been subjected to one-electron oxidation. 17,122,131 xhe common feature of the optical absorptions attributable to the intramolecular radical cations derived from these compounds indicates that interaction occurs mainly between two of the sulfur atoms. For example, max = 600 and 610 nm for the radical cations from 1,3-dithiane and 1,3,5-trithiane, respectively. For the two transients derived from 2,5-dithiaheptane and 1,4,7-trithiacyclononane, respectively, even the same max = 525 nm has been measured. Some tailing on the low energy side and broadening of the absorption bands in the trithia systems suggests, however, some small additional influence by the other sulfurs on the electronic energy levels. This conclusion is fully in line with photoelectron spectroscopy data. 32...
