How can I convert micrometer (μm) values to inverse centimeter (cm-1) and vice-versa in Infrared spectra? This question of how to convert from micrometers to inverse centimeter come up from time-to-time, and I think it might be helpful to have a script that simply address to unit conversion.
Convert micrometers to inverse centimeters
Calculation behind the script:
In the Infrared spectrometry, wavelength is commonly reported in microns / micrometers (μm), and wavenumber is reported in inverse centimeters (cm-1).
- 1 m = 100 cm = 106 μm
- 1 cm = 104 μm
- X cm-1 = 104 / Y μm
- Y μm = 104 / X cm-1
