Formic acid and dimethyl ether are combined in a supersonic expansion to form a molecular adduct with the two subunits held together by a "classical" OH⋯O hydrogen bond and a bifurcated weak CH2⋯O hydrogen bond. The rotational spectra of the parent and of two 13C isotopologues in natural abundance show that the complex has Cs symmetry, with the heavy atom symmetry planes of HCOOH and (CH3)2O perpendicular to each other.

Abstract

Formic acid and dimethyl ether are combined in a supersonic expansion to form a molecular adduct with the two subunits held together by a "classical" OH⋯O hydrogen bond and a bifurcated weak CH2⋯O hydrogen bond. The rotational spectra of the parent and of two 13C isotopologues in natural abundance show that the complex has Cs symmetry, with the heavy atom symmetry planes of HCOOH and (CH3)2O perpendicular to each other.
