N2 - The Osingle bondH⋯O and Osingle bondH⋯S hydrogen bonds were investigated by gas phase FTIR spectroscopy of alcohol–dimethylether and alcohol–dimethylsulfide complexes, with alcohols of increasing hydrogen bond donor strength; methanol (MeOH), ethanol (EtOH) and 2,2,2-trifluoroethanol (TFE). The TFE complexes are more stable and form stronger hydrogen bonds compared to complexes with MeOH and EtOH, which are comparable, and only for the stronger hydrogen bond donor (TFE) are the small differences in acceptor molecules highlighted. The equilibrium constant for complex formation was determined from the experimental and calculated intensity of the OH-stretching transition. The interactions are illustrated by theoretical calculations and topological analysis
