The molecular beam Fourier transform microwave spectrum of 1,4-dioxane-trifluoromethane has been assigned and measured. The two subunits form a cage stabilized by one C-HâââO and two C-HâââF weak hydrogen bonds. The C-HâââO link involves the axial lone pair of one of the two equivalent ring oxygens, while the two C-HâââF bridges connect trifluoromethane to the two axial hydrogens in positions 3 and 5.

Abstract

The molecular beam Fourier transform microwave spectrum of 1,4-dioxane-trifluoromethane has been assigned and measured. The two subunits form a cage stabilized by one C-HâââO and two C-HâââF weak hydrogen bonds. The C-HâââO link involves the axial lone pair of one of the two equivalent ring oxygens, while the two C-HâââF bridges connect trifluoromethane to the two axial hydrogens in positions 3 and 5. The dissociation energy has been estimated from the DJ centrifugal distortion parameter to be 6.8 kJ/mol.
