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. Introduction to Spectroscopy. 2. Spectroscopy. is the study of the interaction of matter with the electromagnetic spectrum. Electromagnetic radiation displays the properties of both particles and waves. Electron can behave like a tiny bar magnet.. Atomic nucleus can spin and behave as a tiny bar magnet. These . spinning nuclei generate tiny magnetic . fields. Any nucleus will spin (odd mass or odd atomic number. Mass Spectrometry . Carbon-13 NMR. Proton NMR. Chromatography . 1. Infrared Spectroscopy. Absorption of infrared radiation causes bonds to vibrate. Different bonds absorb different wavelengths. These can be identified using the table on the data sheet. .
