Abstract:
The Raman spectra of formaldehyde, acetaldehyde, propionaldehyde and n-butyraladehyde (CnH2nO,n = 1, 2, 3, 4) were obtained by portable Raman spectrometer. The molecules of the four aldehydes were calculated by density functional theory (DFT). By comparing the calculated result and the experimental result, the bands of these Raman spectra were assigned. And the Raman spectra of these aldehydes molecules were analyzed and compared. These aldehydes could be real-time rapidly identified by Raman spectroscopy technology.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
