Shape and non-bonding interactions in the formic acid-difluoromethane complex by rotational spectroscopy
Abstract:
The rotational spectrum of the formic acid-difluoromethane complex was measured by using supersonic-jet Fourier transform microwave spectrometer. Experimental results and ab initio calculations support a conformation formed through a relative strong OH⋯F and a bifurcated weak CH2⋯O hydrogen bonds. The distances of the non-bonding interactions were determined to be 1.960(2) Å and 2.797(3) Å for OH⋯F and CH2⋯O, respectively. The dissociation energy of the complex is estimated to be about 1346 cm-1. The bonding nature of the intermolecular interactions was revealed by non-covalent interaction analysis and electron density difference analysis.
