CHAPTER 13 Infared Spectroscopy 13.1 – Electromagnetic Radiation Spectroscopy is the study of the interaction of electromagnetic radiation (light) with molecules Light is characterized by its wavelength ( λ ) which is the distance of one complete cycle of the light wave – the distance between successive crests. Light is also characterized by its frequency ( v ) which is the number of wave cycles that pass a point in a second. Units: seconds -1 , hertz (Hz) The product of the wavelength times the frequency equals the
