I know you're getting really excited at this point. What I'm going to do is introduce this cumulative practice problem and then I'll have you guys try it yourselves. I want you to draw the entire NMR spectrum for this molecule. Now what you're going to notice is that ...

It's a spectrum, not a graph.There is a good chapter on this in Organic Chemistry, by Clayden, Greeves, Warren & Wothers. It walks you through it nicely. It's well worth buying this book so you always have it to hand.For more advanced treatment, check out some of the oxford chemist...

It applies to solving proton NMR problems also in which students must deduce information from the NMR spectrum. This includes looking along the X-axis in the NMR spectrum to determine chemical shift values and the use of peak shape to determine splitting patterns and integration. That is, ...
Fig. 2. The 1H NMR spectrum of PNIPAM dissolved at 10 mM monomer concentration in 200 mM NaSCN solution in D2O recorded in the eNMR sample cell depicted in Fig. 1b. As a third and most important advantage, the circular cross-section of the sample tube and the absence of the inner ca...
Once all 1H-chemical shifts are properly obtained, the 1D 1H-NMR spectrum (Figure 2B) can be completely assigned accordingly, and a table of 1H-chemical shifts can be filled up. Furthermore, through a carbon-related experiment such as the heteronuclear single quantum coherence (HSQC) spectrum,...
