Measurement principle of spectroscopy to analyse molecular properties based on vibrations (bond stretching or deformation modes) in chemical species.
Note: Typically, vibrational spectroscopy uses electromagnetic radiation lower in energy than the visible spectrum i.e.,
infrared or near
infrared (see table).
