6. NMR Spectra of Isomers
About this Lecture
In the sixth and final mini-lecture, we apply the knowledge from previous mini-lectures on chemical shift, coupling, integration, and de/shielding to link NMR spectra with certain organic isomers. We also learn that because of the different arrangements of atoms in space, isomers will have different NMR spectra
In this course, Dr Danny Allwood (Sheffield Hallam University) introduces the concept of NMR spectroscopy, a ubiquitous analytical tool used in all fields of chemistry to determine the structure of compounds. We start by: (i) investigating two types of NMR based on certain nuclei, 1H and 13C, and the sorts of information we can gather from NMR spectra of these nuclei; then (ii) learning about the different regions of a given NMR spectrum, understanding that certain environments and functional groups are likely to be found to be within a defined region of chemical space; (iii) and then beginning to understand why this happens; before (iv) moving onto the concept of integration, specifically with 1H spectra; and then (v) understanding how nuclei in adjacent environments affect each other’s peaks on a spectrum by a process known as coupling; before finally (vi) showing the NMR spectra of isomers, and realising their differences and understanding why this happens.
Dr Danny Allwood joined Sheffield Hallam University from the University of Cambridge, where he undertook a PhD (2008-2012) and post-doctoral research (2012-2015) with Professor Steven V. Ley CBE FRS. Prior to this, he attained my undergraduate degree at the University of Warwick (2004-2008). His current research programme is focused on the development of practical synthetic and catalytic organic transformations.
