Article abstract of DOI:10.1016/j.cplett.2009.12.025

Structural and energetic features of the complex 1,4-difluorobenzene-ammonia have been investigate by rotational spectroscopy. The complex adopts a σ configuration, with the nitrogen of ammonia in the plane of the aromatic ring. Two weak hydrogen bonds, C-H?N and N-H?F, represent the linkages between ammonia and 1,4-difluorobenzene.
