[Abstract]:With the further study of solution theory, solvent chemistry has attracted wide attention. The study of the properties of solution at molecular level, such as ion-ion association, ion-intermolecular solvation and solvent microstructure, is of great significance for the development of modern biochemistry. It is helpful to the research of controlling ion movement in solution and biological environment and plays an important role in the study of spatial structure of solution molecules, material science and life science. In this paper, based on the previous work, the system of methamphetamine-single solvent and double solvent solution was used as the research object, and the infrared spectrum was used. The microstructural changes of methamphetamine in solvent system were investigated and analyzed by fluorescence spectroscopy and theoretical calculation. The internal circulation and poisoning mechanism of methamphetamine were discussed. The main contents are as follows: 1. The change of solution system of methamphetamine in single solvent and mixed solvent was studied by fluorescence spectroscopy. Based on the analysis and calculation of the solvation peak in the spectrum, the influence of the weak interaction between molecules in the solution system on the microstructure of the substance is discussed. 2. Combined with quantum chemical calculation, the optimal structure model of solvated structure was obtained. The possible configuration of the microstructure of methamphetamine in single and double solvents was discussed, and the change of intermolecular chemical bond was verified by IR spectra. The effect of ethanol on the circulation of methamphetamine was discussed. The distribution of methamphetamine in mice was studied by establishing a model of methamphetamine induced poisoning in vivo. It was concluded that methamphetamine spread widely in human tissues, especially in the brain. The mechanism of methamphetamine poisoning was discussed by theoretical calculation.
