Infrared Spectrum, Structure, and Thermodynamic Properties of Trifluoramine Oxide, NF3O

Abstract

The infrared spectrum of NF₃O is reported. The general appearance of the spectrum establishes that the molecules has C_3v symmetry. The bands at 1691, 743, 528, 883, 558, and 400 cm⁻¹ are assigned as the fundamental frequencies. The rotational spacing of ν₂ was used to determine the rotational constant, B=0.19 cm⁻¹. Assuming tetrahedral angles and r(NO) = 1.15 Å with this rotational constant gives an estimate of r(NF) = 1.48 Å.
