ft-raman spectra of saffron (crocus sativus l.) with a partial assignment is reported. based on the raman data, it is concluded that main pigments in saffron are crocins and crocetin. it is proposed that the quickly attainable ft-raman spectrum of solid saffron, may be used as a means of saffron standardization.

We have studied the Fourier Transform Infrared (FT-IR) and the Fourier transform Raman (FT-Raman) spectra of stanozolol and oxandrolone, and we have performed quantum chemical calculations based on the density functional theory (DFT) with a B3LYP/6-31G (d, p) level of theory. The FT-IR and FT-Raman spectra were collected in a solid phase. The consistency between the calculated and experimental ...

The FT-IR, FT-Raman and SERS Spectra of 1-Chloro 4-Flurobenzene (C6H4CLF) have been recorded in the range 4000-400cm -1 , the optimized geometry,frequency and intensity of the vibrtional bands of C6H4CLFhave been obtained by DFT levels of theory with complete relaxation in the 6-311**G basis sets. A complete vibrational assignment, aided by the theoretical frequency analysis, has been proposed....

FT Raman spectroscopy was used for the investigation of cellulose and cellulose derivates. Lattice structures of cellulose, polymorphic modifications I and II, as well as amorphous structure were clearly identified by means of FT Raman vibrational spectra. Chemometric models were developed utilizing univariate calibration as well as methods of multivariate data analyses of the FT Raman spectral...

The ultraviolet spectra (UV) spectra of the title molecule in the region 800-200 cm -1 . Utilizing the observed FT-IR and FT Raman spectra data, a complete vibrational assignments and analysis of the fundamental m...

We propose a new approach to broadband Stimulated Raman Scattering (SRS) spectroscopy and microscopy based on time-domain Fourier transform (FT) detection of the stimulated Raman gain (SRG) spectrum. We generate two phase-locked replicas of the Stokes pulse after the sample using a passive birefringent interferometer and measure by the FT technique both the Stokes and the SRG spectra. Our appro...

We have been successful in adapting Fourier transform (FT) Raman accessories and spectrophotometers for sensitive measurements of the photoluminescence (PL) spectra of photovoltaic materials and devices. In many cases, the sensitivity of the FT technique allows rapid room-temperature measurements of weak luminescence spectra that cannot be observed using dispersive PL spectrophotometers. We pre...

The Fourier transform gas phase (5000-400 cm), solid phase (4000-400 cm) infrared spectra as well as Raman spectra (3500-50 cm) of 1,3-dimethylbarbituric acid have been recorded. Quantum chemical calculations of energies, geometrical structure and vibrational wave numbers of 1,3-dimethylbarbituric acid have been made by density functional method with 6-31G(d,p) as basis set. The best level of t...
