Considerable NMR work has been done over the past four years by Dawson, since joining the section, in structural characterization of new designer amphetamines as well as in the use of chiral shift reagents to differentiate between optical isomers of both ethical and illicit drugs while simultaneously obtaining molecular spectroscopic evidence to verify the authenticity of the examined substances.
