在这项调查中，吸附的苯甲腈在空气/水界面上的振动和频光谱解决。利用ppp和ssp偏振组合，作者检测到的氰基（CN）基团的对称伸缩模式，并计算在界面上的苯甲腈的取向。此外，吸附等温线确定的超极化率元素通过改变本体苯甲腈浓度。通过拟合该等温线得到吸附能。这项工作将增加我们对环境中苯甲腈的保留，降解和光解相关化学过程的理解。
In this investigation, the adsorption of benzonitrile at the air/water interface was addressed using vibrational sum-frequency spectroscopy. Using ppp and ssp polarization combinations, the authors detected the symmetric stretching mode of the cyano (CN) group and calculated the orientation of benzonitrile at the interface. In addition, the adsorption isotherm was determined in terms of the hyperpolarizability element by varying the bulk benzonitrile concentration. The adsorption energy was obtained from fitting this isotherm. This work will add to our understanding of chemical processes relevant to retention, degradation, and photolysis of benzonitriles in the environment.
