How do I convert cm-1 (wavenumbers) to µm (microns)?
Wavenumber is a convenient measure of the frequency of coherent electromagnetic radiation and has units of cm-1. Wavenumbers can be pictured as a measure of the number of wavelengths that are present in 1cm of length. If the wavelength of radiation is 1cm, it has one wave in 1cm of length. We know from the relations ship between frequency and wavelength that f = c/λ and therefore 1 cm-1 = 30 GHz.
