The Influence Of Hydrogen Bond On The Raman Spectrum Of S=O In DMSO Aqueous Solution

There is an increasing interest in the search of C-P and H-B in the field of Materials Science, Chemistry and Life Science. The study of C-P in solution is more important recently.We have taken measurements of the Raman Spectrum of DMSO in the solution of aqueous solution and CCl₄ solution, respectively. Firstly, there exists complex compounds based on hydrogen bond in DMSO aqueous solution. Secondly, in room temperature, S=O bond exhibits double peaks at 1010cm^-1and 1060 cm^-1, respectively. On Raman peak at 1010cm^-1corresponds to S=O bond of DMSO in the complex compound of DMSO aqueous solution. The other Raman peak at 1060cm^-1 denotes S=O of DMSO in the absence of the interaction between DMSO and water. We have verified the complex compounds based on the hydrogen bond when the S=O bond interacts with water molecules, using the method of changing the concentration of CCl₄ solution. And a further research of the influence of the complex compound based on the hydrogen bond on Raman Spectrum has been made.The novel results are listed in the following:1. In room temperature, S=O bond exhibits double peaks at 1010cm^-1and 1060 cm^-1, respectively. And some theoretic explanations are also given.2. Using the method of changing the concentration of CCl₄ solution. And a further research of the influence of the complex compound based on the hydrogen bond on Raman Spectrum has been made.This paper contributes to the research of the structure and properties of the molecules with S=O bonds. However, there also exist some theoretical problems to deal with.
