The structure of N2O–HF

Abstract

The rotational spectra of four isotopes of the weakly bound complex N2O–HF have been measured by molecular beam electric resonance spectroscopy. The following spectroscopic constants and structural parameters were derived from the observations: In the average structure, the N2O axis makes an angle of ∼47° with a line rc.m. drawn between the centers of mass of the two submolecules. HF is hydrogen bonded toward the oxygen on N2O to form an angle of ∼31° with the center of mass line.
