用傅里叶变换光谱仪测量了羟基自由基OH在1850 ~ 9000 cm ~（-1）之间的红外光谱。的源，一个氢-臭氧扩散火焰，被设计成研究的OH Meinel带的旋转振动水平的激发下，类似于那些在高层大气中产生的夜间OH气辉发射的条件。观察到23个条带：Δ upper = 1序列中9个条带，Δ upper = 2序列中9个条带，Δ upper = 3序列中5个条带。一个全球性的非线性最小二乘拟合1696线产生的分子参数的标准偏差为0.003 cm-1。计算了项值，并预测了近红外中Δ upp = 3，4，5，6序列的跃迁频率。
The infrared spectrum of the hydroxyl radical OH, between 1850 and 9000 cm-1, has been measured with a Fourier transform spectrometer. The source, a hydrogen-ozone diffusion flame, was designed to study the excitation of rotation-vibration levels of the OH Meinel bands under conditions similar to those in the upper atmosphere which produce the nighttime OH airglow emission. Twenty-three bands were observed: nine bands in the DELTAupsilon = 1 sequence, nine bands in the DELTAupsilon = 2 sequence, and five bands in the DELTAupsilon = 3 sequence. A global nonlinear least-squares fit of 1696 lines yielded molecular parameters with a standard deviation of 0.003 cm-1. Term values are computed, and transition frequencies in the DELTAupsilon = 3, 4, 5, 6 sequences in the near-infrared are predicted.
