Nitrogen monofluoride (fluoroimidogen) is a metastable species that has been observed in laser studies. It is isoelectronic with O₂. Like boron monofluoride, it is an instance of the rare multiply-bonded fluorine atom.^[1]^[2] It is unstable with respect to its formal dimer, dinitrogen difluoride, as well as to its elements, nitrogen and fluorine.

Nitrogen monofluoride is produced when radical species (H, O, N, CH₃) abstracts a fluorine atom from nitrogen difluoride (NF₂). Stoichiometrically, the reaction is extremely efficient, regenerating a radical for long-lasting chain propagation. However, radical impurities in the end product also catalyze that product's decomposition. Azide decomposition offers a less-efficient but more pure technique: fluorine azide (which can be formed in situ via reaction of atomic fluorine with hydrazoic acid) decomposes upon shock into NF and N₂.^[3]^[4]

Many NF-producing reactions give the product in an excited state with characteristic chemiluminescence. They have thus been investigated for development as a chemical laser.^[4]^[5]
