In my first two posts on using 1D and 2D NMR methods to assign the peaks of quinine (Figure 1), I looked at the 1H and 13C spectra. Figure 1. Structure of quinine In this post, I’m moving on to look at the 1H-13C HSQC spectrum. It’s worth spending a brief moment recapping …

In my last blog post I introduced silicon NMR on Spinsolve and showed a variety of 1D 29Si{1H} and 29Si-1H DEPT spectra. In this post I’m moving on to talk about some 2D experiments that are useful for silicon studies. One of the most useful and widely used of those is the 1H-29Si HMBC experiment, which …
One of the most widely-used 2D techniques these days is the HSQC (Heteronuclear Single Quantum Correlation) experiment. In the world of “small molecule” NMR, HSQC is most frequently used to correlate protons and carbons over one chemical bond.
