本文用多重内反射红外光谱研究了氢原子与天然IIa型金刚石表面在673 K下的反应。在2880 cm−1处观察到单一的红外吸收带，并归因于sp3杂化表面碳上的C-H伸缩模式。谱带在1073和1173 K之间的表面温度下是稳定的，并且当脱氢表面暴露于原子氘时不存在。
Multiple internal reflection infrared spectroscopy is used to investigate the reaction of atomic hydrogen with a polished, natural type IIa diamond (110) dehydrogenated surface held at 673 K. A single infrared absorption band at 2880 cm−1 is observed and is attributed to the C‐H stretching mode on an sp3 hybridized surface carbon. The band is stable up to surface temperatures between 1073 and 1173 K, and is absent when the dehydrogenated surface is exposed to atomic deuterium.
