Abstract
Acetic acid solution can emit visible fluorescence when induced by UV-light. With emitting spectrum profiles dissimilar on the whole, the fluorescent intensity changes too when the excited light alters from 230nm to 300nm. There are two spectral bands on the whole, one central wavelength is located at 307nm and the other is at 400nm. The relationship between the fluorescence relative intensity and the excited-light wavelength is described in polynomial fit. The optimal excited light is obtained both by the experiment data and the polynomial fit of the data. Investigation on the intrinsic fluorescence spectrum of acetic acid solution and its characteristics will contribute to the study of the fluorescence spectra when acetic acid serves as a solute and hydrolysis catalyst. Especially, this study will also help to offer the experiment basic for the theoretic research of the interaction of acetic acid and water molecule.
