Chemistry of the SO bond. Part III. Nuclear magnetic resonance and infrared studies on phenylethylene sulphites
The 100 MHz 1H n.m.r. spectra of phenylethylene sulphites have been examined for solutions in several solvents. Interpretation of the 1H n.m.r. spectra together with an i.r. study of the SO stretching frequency in a number of solvents suggests the existence of a basically similar conformation in solution for each of these sulphites, as suggested for the methylethylene sulphites.
