分子间和分子内的氢键对决定分子结构和物理化学性质具有重要作用,但对于具有非典型氢键结构的分子来说,这一点很容易被忽视。对硝基硫酚(PNTP)在固态和溶液态下的拉曼光谱的差异是由氢键作用引起的。理论计算和实验结果的一致性表明,PNTP在固态时,分子间氢键形成八原子环结构(8),在2550 cm−1处的特征S-H-O伸缩振动模式证实了这一点;在溶液态时,S-H-O氢键的断裂诱导了2590 cm−1处的S-H伸缩振动。我们的研究结果可能为分子间氢键的鉴定提供一种简单、快速的方法。
Inter- and intra- molecular hydrogen bonding plays important role in determining molecular structure, physical and chemical properties, which may be easily ignored for molecules with a non-typical hydrogen bonding structure. We demonstrated in this paper that the hydrogen bonding is responsible for the different Raman spectra in solid and solution states of p-Nitrothiophenol (PNTP). The consistence of the theoretical calculation and experiment reveals that the intermolecular hydrogen bonding yields an octatomic ring structure (8) of PNTP in the solid state, confirmed by the characteristic S-H---O stretching vibration mode at 2550 cm−1; when it comes to the solution state, the breakage of hydrogen bond of S-H---O induced the S-H stretching vibration at 2590 cm−1. Our findings may provide a simple and fast method for identifying the intermolecular hydrogen bonding.
