Characterization of gas-phase thorium nitride
The Journal of Chemical Physics, 2019 Properties of gas-phase thorium nitride, ThN, have been experimentally determined from a combined optical and microwave spectroscopic study. An intense band near 555 nm has been assigned as the [18.0]1.5–X2Σ+ (0,0) transition and recorded at high resolution in the presence of static electric and magnetic fields.

Internal nitride formation during gas-phase thermal nitridation of titanium [PDF]
Scripta Materialia, 2009 Titanium nitride surface layers were prepared by gas-phase thermal nitridation of pure titanium in an ammonia atmosphere at 1373 K for different times. In addition to the surface nitride layer, nitride/hydride formation was observed in the bulk of the specimen.
