A hollow cathode discharge with a copper nickel cathode (Cu50Ni50) was operated in an Ar/H/N gas mixture. Optical emission spectroscopy revealed the formation of NH radicals, which serve as precursors for NH formation. Ion mass spectrometry showed the formation of NH and NH ions indicating NH formation. Gas samples taken at the exhaust of the vacuum system were analyzed by Fourier transform infrared spectroscopy. Clear evidence for NH formation was obtained from these measurements.
一个带有铜镍阴极（Cu50Ni50）的空心阴极放电装置在氩/氢/氮气体混合物中运行。光发射光谱显示形成了NH自由基，其作为NH形成的前驱体。离子质谱表明形成了NH⁺和NH₂⁺离子，这表明有NH形成。通过傅里叶变换红外光谱对在真空系统排气口采集的气体样品进行了分析。从这些测量中获得了NH形成的确凿证据。
