In the paper we report the first observation of the vibrational spectrum in the B-H stretching region in the gas phase for a dihydrogen bonded complex. The appearance of three transitions for the B-H stretching modes of a (di)hydrogen-bonded complex involving borane-trimethylamine indicates the lowering of the symmetry on the BH3 group upon interaction with phenol. Further, the shift in the O-H stretching frequency indicates that phenol is hydrogen bonded to borane-trimethylamine. The two sets of the present data establish, unequivocally, the formation of O-H...H-B dihydrogen-bonded complex between phenol and borane-trimethylamine.
在本文中，我们报道了对气相中双氢键合配合物B-H伸缩区域振动光谱的首次观测。涉及硼烷-三甲胺的（双）氢键合配合物的B-H伸缩模式出现三个跃迁，这表明与苯酚相互作用时BH₃基团的对称性降低。此外，O-H伸缩频率的位移表明苯酚与硼烷-三甲胺形成了氢键。目前的两组数据明确证实了苯酚与硼烷-三甲胺之间形成了O-H...H-B双氢键合配合物。
