利用双色共振增强多光子电离（REMPI）和零动能（ZEKE）光电子能谱研究了苯酚-乙醇复合物的氢键。REMPI光谱显示的振动结构可以归属于S1原点上的低频分子间模式，并与S1电子态的分子内（苯酚局域）振动相结合：对REMPI光谱低能区的重新解释给出了S1态分子间伸缩的频率为162 cm-1
The hydrogen-bonded phenol-ethanol complex has been studied using both two-color resonant-enhanced multiphoton ionization (REMPI) and zero-kinetic-energy (ZEKE) photoelectron spectroscopy. The REMPI spectrum shows vibrational structure which can be assigned to low-frequency intermolecular modes on the S 1 origin and in combination with intramolecular (phenol-localized) vibrations of the S 1 electronic state: a reinterpretation of the low-energy region of the REMPI spectrum gives the frequency of the intermolecular stretch in the S 1 state as 162 cm -1
