In this particular case, the Raman image is rendered through a color coded plot of Raman signal strength of the cor-responding color bracketed Raman shift
Raman shifts are typically reported in wavenumbers, which have units of inverse length, as this value is directly related to energy. In order to convert between spectral wavelength and wavenumbers of shift in the Raman spectrum, the following formula can be used: where Δν̃ is the Raman shift expressed in wavenumber, λ0 is the excitation wavelength, and λ1 is the Raman spectrum wavelength. Most commonly, the unit chosen for expressing wavenumber … Web2. Predict the number of peaks for the IR and Raman spectra. 3. Convert the experimental peak positions from wavelength to wavenumbers. The Raman shift is the difference between the wavenumber of the laser line and the wavenumber of the observed peak (Since these are Stokes lines, the Raman shift is always >0). 4.
