Abstract

Abstract: The dynamic Fourier spectrometer model for Raman scattering (RS) is developed. The working spectral range is 800–1050 nm. The excitation source is the laser with the wavelength λ = 785 nm. In the spectrometer the "white light" channel for summing interferograms over several scans is implemented. Also the reference channel with a sampling frequency of λ / 4 is realised. The developed layout in experiments of the chemical compounds registration is approved. The signal-to-noise ratios for recorded Raman spectra are also calculated. The work shows the RS spectra of stilbene (C14 H12 ) and 1, 4-bis (5-phenyl-2-oxazolyl) benzene (POPOP, C24 H16 N2 O2 ) recorded on the model spectrometer. An experimental research of the registration of the minimum amount of stilbene (C14 H12 ) dissolved in acetone using the Raman spectroscopy method was carried out.
