PPT-Infrared Spectroscopy, Mass Spectrometry, and NMR Spectroscopy

Introduction to Spectroscopy Spectroscopy involves an interaction between matter and light EMR Light can be thought of as waves of energy or packets particles of energy called photons Properties of light waves include wavelength and frequency.
