NMR is a very powerful technique that enables the study of physicochemical, electronic, and structural properties of molecules, looking at the quantum mechanical magnetic properties of an atomic nucleus (specifically, the chemical shift and Zeeman effect on the resonant frequency), in solution as well as the solid state. Nmr spectroscopy 1. Spectroscopy NMR, IR, MS, UV-Vis Main points of the chapter 1. A Hands on Introduction to NMR 22.920 Lecture #1 Nuclear Spin and Magnetic Resonance Introduction - The aim of this short course is to present a physical picture of the basic principles of Nuclear Magnetic Resonance (NMR) spectroscopy and imaging, along with a brief introduction to selected experimental details. Nuclear Magnetic Resonance Spectroscopy Notes adapted by Audrey Dell Hammerich, October 3, 2013 Nuclear magnetic resonance (NMR), as all spectroscopic methods, relies upon the interaction of the sample being examined with electromagnetic radiation, here in the low energy range of radio frequencies (1-1000 MHz). L ECTURE COURSE: NMR S PECTROSCOPY 4 A PPLICATION F IELDS OF NMR S PECTROSCOPY High-resolution NMR spectroscopy … NMR involves the use of magnetic fields and energy to excite nuclei out of an equilibrium state; from the excited state, nuclei relax back to the equilibrium state. January 2015 Page 11 LECTURE NOTE ON SPECTROSCOPY 10.8 Nuclear Magnetic Resonance Spectroscopy (NMRs) according to their mass-to-charge ratio, m/z, and measuring the NMR spectroscopy is based on the measurement of absorption of abundance of the ions formed. Nuclear Spin" Nuclear spin µ = γ I h µ - magnetic moment γ - gyromagnetic ratio I - spin quantum number h - Planck’s constant m I – magnetic quantum number µ" I is a property of the nucleus!
