IR Spectroscopy and FTIR Spectroscopy: How an FTIR Spectrometer …
2024年4月12日 · 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.
