Convert wavelength to raman shift
WebIn order to convert between spectral wavelength and wavenumbers of shift in the Raman spectrum, the following formula can be used: where is the Raman shift expressed in … 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 …
