用红外-紫外双共振光谱和红外光解离光谱分别观察了喷冷苯酚-N-2在神经态和阳离子基态的OH伸缩振动。在中性和阳离子中，OH振动在团簇形成时出现了5 cm(-1)的微小但显著的低频位移，而在阳离子中的低频位移急剧增加到159 cm(-1)。这些结果代表了面内团簇结构的直接证据，其中酚羟基与N-2氢键，这是在零动能光电子研究中提出的[S.R.Haines等人，J.Chem]。太棒了。109,9244(1998)]。(C)1999年美国物理研究所。[S0021-9606(99)02023-1]。
The OH stretching vibration of jet-cooled phenol-N-2 in the neural and cationic ground states was observed by using infrared-ultraviolet double resonance spectroscopy and infrared photodissociation spectroscopy, respectively. The OH vibration showed a small but significant low-frequency shift of 5 cm(-1) upon the cluster formation in the neutral, while the shift drastically increased up to 159 cm(-1) in the cation. These results represent the direct evidence of the in-plane cluster structure, in which phenolic OH is hydrogen bonded to N-2, as was proposed in the zero kinetic energy photoelectron study [S. R. Haines et al., J. Chem. Phys. 109, 9244 (1998)]. (C) 1999 American Institute of Physics. [S0021-9606(99)02023-1].
