最近,美国加利福尼亚州技术学院的科学家们,首次获得了苯(一种非极性憎水性分子)同水形成氢键的直接的确凿证据。在此以前,有好几个研究组曾报导过芳香环同水和其它分子形成氢键的间接证据。天体化学家G.A.Blake和他的合作者,让苯-水这两种组份的气体混合物通过一条狭缝后扩散,得到一种苯-水簇的超声速射流。从分析1:1苯-水络合物的微波光谱可清楚的看出,水

Recently, scientists at the California Institute of Technology for the first time obtained straightforward evidence that benzene, a non-polar hydrophobic molecule, forms hydrogen bonds with water. Prior to this, several groups have reported indirect evidence that aromatic rings form hydrogen bonds with other molecules and other molecules. Celestial chemist G.A. Blake and his collaborators, the benzene-water mixture of the two components of the gas mixture through a slit diffusion to give a supersonic jet benzene-water jet. The microwave spectrum of the 1: 1 benzene-water complex can be clearly seen from the water
