Wavenumber
noun
Wavenumber is the number of wavelengths per unit distance, typically expressed in reciprocal centimeters (cm⁻¹), used mainly in spectroscopy.
In spectroscopy, the wavenumber is an important parameter used to identify molecular bonds.

Often appears as...
- spectroscopic wavenumber
- molecular wavenumber

General
noun
Wavenumber is inversely related to wavelength, whereby an increase in wavenumber corresponds to a decrease in wavelength and vice versa.
As the wavenumber increases, the energy of the photons also increases, indicating shorter wavelengths.

Often appears as...
- energy wavenumber relationship
- wavenumber-energy correlation
