Raman spectra cyclohexane
WebbThe Raman shift values for cyclohexane have been accurately measured and it is widely used as a reference material. The permanently sealed cuvette eliminates the hazards … WebbReagent grade cyclohexane, permanently sealed by heat fusion into a 10 mm quartz cuvette. Compared to atomic emission lines, Raman shift standards offer an easier-to-use alternative for qualifying the wavelength scale of Raman Spectrometers. They are also independent of laser frequency.
