The study of the acetonitrile-water system is very important for understanding binary mixtures leading to powerful solvents with applications in chemistry and environment studies . A more detailed understanding of the acetonitrile-water interaction should consider the important hydrogen-bond interaction. Moreover, the hydrogen bond is a topic of continuing interest in physics, chemistry and biology . For the hydrogen-bonded complexes, where the formation and cleavage of such complexes occurs rapidly, vibrational spectroscopy such as IR and Raman are ideally suited to detect hydrogen bond because they cover both structural and dynamic aspects.[12] Whereas the wavenumber position of a vibrational band, which relates to the corresponding internuclear force constants, is dependent on electronic structure and bonding, the line width contains information about molecular dynamics. As compared to IR spectroscopy, Raman spectroscopy can reveal additional information from a line width analysis.[4] Therefore，Raman spectroscopic studies provide an important tool for qualitative study of solute-solvent interactions. |

A more detailed understanding of the acetonitrile-water interaction should consider the important hydrogen-bond interaction.感觉有点问题 你可以把汉语发一下 For the hydrogen-bonded complexes, where the formation and cleavage of such complexes occurs rapidly 改成 the hydrogen-bonded complexes whose formation and cleavage occur rapidly 会不会要好一些 Whereas the wavenumber position of a vibrational band, which relates to the corresponding internuclear force constants, is dependent on electronic structure and bonding 应改成Whereas the wavenumber position of a vibrational band relates to the corresponding internuclear force constants, is dependent on electronic structure and bonding |

A more detailed understanding of the acetonitrile-water interaction should consider the important hydrogen-bond interaction. Hydrogen-bond interaction should be taken into consideration for a more detailed understanding of the acetonitrile-water interaction. "topic of continuing interest"改成“promising topic"是不是更确切些？ |
