WebAug 16, 2024 · IR spectroscopy is the study of the interaction of IR light with matter, where IR light is characterized by the wavenumber range spanning 12,800 to 10 cm-1. Historically, by convention, IR tends to be described in “wavenumber”, where any wavenumber is inversely proportional to its wavelength. Thus, a shorter wavelength will have a larger ...
