Abstract

The absorption spectra and fluorescence spectra and their haracteristics of iodomethane (CH3I) excited by ultraviolet light were analyzed experimentally. It was found that methyl iodide had a good absorption of 280-375 nm ultraviolet light and obvious fluorescence was emitted at 280-320 nm ultraviolet light excitation; CH3I-toluene mixed solutions with different ratio on volume were excited at the light with the wavelength of 300nm. It was found that the fluorescence intensity gradually increased with the increase of toluene volume ratio and a basic linear relationship was shown. We also measured the fluorescence spectra of the CH3I-ethanol mixed solutions at different wavelengths of ultraviolet light, and variation of the fluorescence intensity of the CH3I-ethanol solutions with different mixing ratio is also different. In additional, we are giving the mathematical expression of the fluorescence peak position of the mixed solution. This give some reference significance of the solvent effect and the study of CH3I molecular dynamics by the spectrum.
