Solid-state NMR (ssNMR) spectroscopy is a special type of nuclear magnetic resonance (NMR) spectroscopy, characterized by the presence of anisotropic (directionally dependent) interactions. NMR is a branch of spectroscopy and so it describes the nature of the energy levels of the material system and transitions induced between them through absorption or emission of electromagnetic radiation. Nuclear Magnetic Resonance (NMR) spectroscopy has made a tremendous impact in many areas of chemistry, biology and medicine. RF detector. Radio frequency bridge (single coil detection) 2. 4. Underlying principal of infrared spectroscopy is based upon the molecular vibration which is further composed of the stretching and the bending vibration of a molecule.
