Visit our sponsor at www.chemglass.com Multinuclear NMR Multinuclear NMR Spectroscopy General Information Presumably, all of us are familiar with NMR ( N uclear M agnetic R esonance) spectroscopy from our organic and analytical laboratory courses/experience. Such experience is generally limited to H and maybe C NMR. There are actually dozens of other nuclei that are also amenable to study using NMR. Part of the joy of Inorganic Chemistry is that we need not limit ourselves to C and H in either syntheses or spectroscopy! NMR spectra of nuclei with a spin quantum number, I, of 1/2 are easiest for us to understand because they obey the same kind of coupling behavior we see for the most common I = 1/2 nucleus, H. Spins with I = 1 to 9/2 are also amenable to study and their interpretation is not all that much more difficult. Just because a nucleus has a non-zero spin does not automatically mean that we can obtain an NMR spectrum of that nucleus. There are at least four other factors we must consider: - Isotopic Abundance . You can't see it if it isn't there. Some spin active nuclei such as F are 100% abundant ( H is 99.985%), but others such as
