NMR - what is it? Why do we need it? by Miss Wrigley https://padlet.com/Miss_Wrigley/NMR Describe what NMR means to you - do not just state that is it Nucelar Magnetic Resonance! en-us 2014-06-24 09:08:46 UTC 2017-05-17 08:23:29 UTC hello@padlet.com START OF LESSON Miss_Wrigley https://padlet.com/Miss_Wrigley/NMR/wish/30115775 2014-06-25 09:24:06 UTC https://padlet.com/Miss_Wrigley/NMR/wish/30115775 END OF LESSON Miss_Wrigley https://padlet.com/Miss_Wrigley/NMR/wish/30115781 2014-06-25 09:24:17 UTC https://padlet.com/Miss_Wrigley/NMR/wish/30115781 Saskia??? https://padlet.com/Miss_Wrigley/NMR/wish/30117626 A way of identifying unknown compounds- it is the most effective way to identify compounds

exposed to a magnetic field in which the Hydrogen atoms change energy levels? The different energies possessed by the photons helps determine the position of the hydrogens in the molecule (The surrounding atoms affect the photon given off), making NMR great for determining the structure of a molecule that has a known molecular formula.... I think. 2 types of NMR (Hydrogen (High resolution proton) and Carbon-13).
