Vyvyanlb Department of Chemistry, University of Minnesota, Minneapolis, Minnesota 55455 Received March 9, 1994* The ability to deduce the proper set of coupling constant ( ) J values from a complex first-order multiplet in a I NMR spectrum is an extremely important asset. This is particularly ...
A 13C{1H}-NMR spectrum is defined as a type of spectroscopy technique used in chemistry to analyze the carbon and hydrogen atoms in a compound by measuring the chemical shifts of the nuclei in a magnetic field. AI generated definition based on: Journal of Organometallic Chemistry, 2011 ...
