10% strychnine in cdcl3 step 1. The cdcl3 signal is a 1:1:1 triplet due to the j coupling to the deuteron which is a spin i=1 nucleus having three energy levels. It will be helpful to view an expanded section of this spectrum from δ 0.0 to 50.0 ppm, and this will be presented by clicking the high field expansion button.

13c nmr provides better results than 1h nmr for the resolution of peaks obtained from high molecular mass and very viscous polymers, but the instrumentation required is more expensive and a larger amount of sample and longer analysis times are involved.

The chemical shifts (d) of solvent signals observed for 1h nmr and 13c nmr spectra are listed in the following table. Incomplete deuteration of the solvent, there is a trace of chcl3 in the solvent. Also, the op has (tacitly) correctly assumed that the peak at 0 ppm is tms. Analyses of these nmr data for the title 5,5.
