Proton Chemical Shifts

The position of the proton signals in the nuclear magnetic resonance spectrum of sulfanes (H2Sx) is dependent on the sulfur chain length, the sulfane concentration, and the temperature. These proton chemical shifts are interpreted in terms of sulfane–sulfane interactions and intramolecular hydrogen bonding in sulfanes. Supporting evidence is provided by the position and appearance of the SH-absorption bands of the sulfanes in the infrared, which also establishes the existence of sulfane–solvent interactions.It is concluded that sulfanes participate in hydrogen bonding interactions and it is suggested that there may be a special type of intramolecular hydrogen bonding operative in H2S3.
