OH自由基的（2+1）共振增强多光子电离-光电子能谱（REMPI-PES）研究在81 300和88 900 cm−1之间的双光子能量区域进行。通过过氧化氢或甲酸的光解产生平移和旋转热OH自由基。在该区域（距基态81 815.8和87 643.7 cm−1）中已知的D2 <$−（v '= 0-2）和迄今未观测到的3 2 <$−（v'= 0）中间态具有主要的里德伯特征。从REMPI谱中的转动结构中导出了这些态的物理参数。
A (2+1) resonance‐enhanced multiphoton ionization–photoelectron spectroscopy (REMPI‐PES) study of the OH radical has been carried out in the two‐photon energy region between 81 300 and 88 900 cm−1. Translationally and rotationally hot OH radicals are generated via photodissociation of hydrogen peroxide or formic acid. The known D 2Σ− (v’=0–2) and hitherto unobserved 3 2Σ−(v’=0) intermediate states in this region (at 81 815.8 and 87 643.7 cm−1 above the ground state) are shown to possess predominant Rydberg character. From the rotational structure in the REMPI spectrum physical parameters have been derived for these states.
