A C-13-2D EXSY experiment on a C-13-enriched sample of H2OS3(CO)(11) at 220 K and at the observation frequency of 100.25 MHz indicates that this compound is involved in an intramolecular exchange between two enantiomeric structures prior to undergoing the axial/equatorial hydride motion typical of this type of adduct.

Abstract
A C-13-2D EXSY experiment on a C-13-enriched sample of H2OS3(CO)(11) at 220 K and at the observation frequency of 100.25 MHz indicates that this compound is involved in an intramolecular exchange between two enantiomeric structures prior to undergoing the axial/equatorial hydride motion typical of this type of adduct.
