| Abstract: | | 1. |
The IR spectra of a solution of mercaptoethanol in CCl4 and in gas-phase mercaptoethanol have  XH bands for free OH and SH groups and OH...S and SH...O groups in intramolecular hydrogen bonds. This indicates a conformational multiplicity of the ME molecules.
| | 2. |
A molecular mechanics calculation indicates the possibility of conformational multiplicity for mercaptoethanol. The energy of the intramolecular OH...S hydrogen bond was evaluated.
