Raman wavelength wavenumber converter
Webbwhere λ is the wavelength. It is sometimes called the "spectroscopic wavenumber". It equals the spatial frequency. A wavenumber in inverse cm can be converted to a … Webb29 maj 2015 · Not only in IR spectroscopy. Wavenumber is unit of energy and therefore you can directly deduce the difference of energy between states. In addition, humans like to think in acceptably small numbers (0.01 - 10,000). Wavenumber allows this for IR and conveniently supplements the eV unit in small energy separations range.
