1H spectrum of natural abundance NH4Cl (1.5 M) in 1M HCl/H2O showing coupling to 14N as a triplet and coupling to 15N as a weak doublet. Coupling constants for triplet and doublet are 52.4 Hz and 73.5 Hz, respectively, as shown in figure.
Please explain me how to index to these peaks to protons (or origin of these peaks).
Thanks!
