Title: | Electron paramagnetic resonance study of .pi. system interaction in dithiin derivatives | Authors: | Carvalho, Maria de Conceicão Ramos de Eargle Jr., Dolan H. |
Issue Date: | Jun-1973 | Publisher: | American Chemical Society | Citation: | The Journal of Physical Chemistry. 77:13 (1973) 1716-1718 | Abstract: | The anion radical of tetracyanodithiin (I) is shown to be a divalent sulfur system in which d-orbital participation in conjugation is negligible. The g value (2.0024) indicates that spin-orbit coupling is very small, and a molecular =ode1 shows that direct A-A overlap of the ethylene moieties is probable. Other S-containing cation and anion systems are compared, including 2,5-diphenyldithiin (IV) and tetracyanothiophene (VI). Large cation g value deviations and small anion deviations of S heterocycles are contrasted with hydrocarbons | URI: | https://hdl.handle.net/10316/10288 | DOI: | 10.1021/j100632a025 | Rights: | openAccess |
