Abstract:The Raman spectra of formic acid,acetic acid,propionic acid and butyric acid have been obtained by experimental detection.The calculated result which was simulated by density functional theory was coincided as the experimental result.The characteristic peaks of the four monobasic acids were analyzed and assigned.The result shows that the Raman spectrum of formic acid was very different from the other three acids;The Raman spectra of the other three acids were similar,but there were significant difference between the wavenumber of the main strongest peaks and the intensity of the subsequent peaks.These monobasic acids could be real-time rapid identified by Raman spectroscopy technology.
Keywords:formic acid  acetic acid  propionic acid  butyric acid  Raman spectra
