FT-Raman Spectra of Saffron (Crocus Stivus L.); A Possible Method for Standardization of Saffron
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.
متن کاملRaman Spectra of a PMMA Microstructured Optical Fibre and Direct Measurement of Its Gain Coefficient
A polymethylmethacrylate (PMMA) microstructured polymer optical fiber (mPOF) is fabricated and characterized. Using the cut-back technique the fiber loss is measured which is higher than the step-index silica fibers. Through a novel experimental scheme, the backward Stokes spectrum of the fabricated mPOF is recorded over a range exceeding 3000 cm‑1 during the cut-back method and compared ...
متن کاملSpectra of diatomic molecules
Clearly N is perpendicular to R, so the projection of J onto R is the same as the projection LR with eigenvalue ¤1 h of L. (We now reserve z for a direction ̄xed in space, and use the subscript R for a component along R). Because total angular moment of an isolated molecule is constant, eigenfunctions of H when L is non-zero will have the quantum numbers J , MJ , ¤, s (to describe the electronic...
متن کاملResonant Raman spectra of molecules with diradical character: multiconfigurational wavefunction investigation of neutral viologens.
The resonant Raman and UV/vis absorption spectra of two diradicaloïd compounds, methyl viologen and phenylene-extended viologen in their neutral state, have been simulated using multiconfigurational wavefunction methods. For methyl viologen, a good agreement with experiment is evidenced for the UV/vis absorption vibronic structure, provided dynamic correlation is accounted for to get the vibrat...
متن کاملDatabase of Standard Raman Spectra of Minerals and Related Inorganic Crystals
Establishing a standard Raman spectral database for minerals and related inorganic crystals is a very important basis for further increasing the applications of Raman spectroscopy in the geosciences. However, the Raman spectral pattern of a crystal is a function not only of its composition and structure but also of the scattering geometry during the measurement. Therefore, the standard Raman sp...
