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. . 1. 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. Spectroscopy . . Is the interaction between matter and electromagnetic radiation (light). . Spectroscopy is commonly used in chemistry to detect, identify, and quantify information about different atoms and molecules. Piet Van Duppen. ISOLDE CERN, Switzerland. IKS-. K.U.Leuven. , Belgium.
