Ultraviolet photoabsorption spectrum of gaseous nitryl fluoride

Abstract

The absorption spectrum of nitryl fluoride (FNO 2) was quantitatively studied over the near u.v.—visible region at room temperature. The absorption obeys Beer's law and is a continuum having photoabsorption cross sections (σ) ranging from (2.2 ± 0.8) × 10 −18 cm 2 at 195 nm to (3.0 ± 2.8) × 10 −20 cm 2 at 300 nm. No appreciable absorption (σ < (3 ± 3) × 10 −20 cm 2) occurs at wavelengths longer than 300 nm.
