Convert raman shift to wavenumber
WebThe Raman spectrum is notated as the intensity of scattered light in the vertical axis and the wavenumber of the Raman shift in the horizontal axis. Raman shift is the shift in wavelength of the inelastically scattered radiation, which provides structural and chemical information. Raman shifted photons can be of lower or higher energy ... Web1. Frequency and Wavelength Units The Raman active vibrational modes are designated by the Raman shift in units of wavenumbers. The two main regions to observe signatures are the fingerprint region that cover the spectral range from ∼ 500 to 1750 cm−1 and the c-h stretch region that cover the spectral range from ∼ 2700 to 3000 cm−1 as ...
