Introduction

Nuclear magnetic resonance (NMR) spectroscopy and Infrared (IR) spectroscopy can often be used in combination to elucidate the structure of unknown compound. Both methods are routinely employed in chemistry research because they are rapid, require only a small quantity of material and are nondestructive. IR spectroscopy provides information leading to the identification of functional groups in a compound, whereas NMR spectroscopy can be used to obtain more specific information regarding the connectivity and structural arrangement of atoms.
