Subtracting the Raman Spectrum of Solvent for Quantitative Analysis
Journal of Raman SpectroscopyABSTRACT Raman spectroscopy is widely employed for quantitative analysis in aqueous solutions, yet it faces a notable challenge: the overlap of water Raman bands, often used as an internal standard, with analyte bands.

Model analysis of the Raman spectrum from fused silica optical fibers
Applied Optics, 1982Abstract : The Raman spectrum from pure silica optical fibers has been analyzed into a set of Gaussian components. Each component used is related to an observed feature of the spectrum, and a residual of about 1% resulted without the use of additional components. Both single- and multi-phonon peaks were fitted.

Theoretical analysis of the resonance Raman spectrum of tryptophan
Journal of Raman Spectroscopy, 1991AbstractThe resonance Raman excitation profiles of tryptophan in the region 240‐200 nm were calculated, taking into account the molecular properties of its chromophore, indole. The relevant quantities such as state displacements and vibronic coupling terms were evaluated by means of quantum mechanical semi‐empirical methods.

The Raman spectra of H2 and HD molecules in simple hydrogen and binary hydrogen-tetrahydrofuran clathrate hydrates have been measured at temperatures as low as 20 K. The rotational bands of trapped molecules in simple and binary hydrates have been analyzed, and the contributions originating from hydrogen molecules in the large cages have been separated

Application of artificial neural network to quantitative analysis of Raman spectrum
SPIE Proceedings, 2006By means of Artificial Neural Network and Back-Propagation algorithm, the multi-component of azo-dyes can be qualitatively and quantitatively analyzed simultaneously, though their Raman spectra are overlapped. This article designed a Back-Propagation algorithm network to analyze the multi-component of azo-dyes (Sudan I and Sudan III). In conclusion,

An analysis of the Raman spectrum of syndiotactic polypropylene. 1. Conformational defects
Polymer, 2001Abstract Spectroscopic features in the Raman spectrum of both crystalline and amorphous syndiotactic polypropylenes are reported which characterize different chain conformations. A normal coordinate analysis was conducted to assist in identifying conformationally sensitive bands in the experimental spectra.

[Laser Raman spectrum analysis of carbendazim pesticide].
Guang pu xue yu guang pu fen xi = Guang pu, 2015Raman signal of solid and liquid carbendazim pesticide was collected by laser Raman spectrometer. The acquired Raman spectrum signal of solid carbendazim was preprocessed by wavelet analysis method, and the optimal combination of wavelet denoising parameter was selected through mixed orthogonal test. The results showed that the best effect was got with
