FAQ

What is the Spectroscopic Wavenumber?
Spectroscopic Wavenumber is the number of wavelengths per unit distance, typically centimeters. Spectroscopic Wavenumber is usually measured using the 1 per Centimeter for Reciprocal Length. Note that the value of Spectroscopic Wavenumber is always positive.
Can the Spectroscopic Wavenumber be negative?
No, the Spectroscopic Wavenumber, measured in Reciprocal Length cannot be negative.
What unit is used to measure Spectroscopic Wavenumber?
Spectroscopic Wavenumber is usually measured using the 1 per Centimeter[cm⁻¹] for Reciprocal Length. 1 per Meter[cm⁻¹], 1 per Kilometer[cm⁻¹], 1 per Mile[cm⁻¹] are the few other units in which Spectroscopic Wavenumber can be measured.
