splitting patterns lastly let’s discuss
Splitting Patterns Lastly, let's discuss why some signals are comprised of only a single peak, called a singlet, while other signals exhibit splitting, and may appear as a doublet, triplet, quartet, quintet, sextet, septet, octet, nonet, etc. Splitting is due to neighboring H's. That is, H's that are separated by 3 covalent bonds are called "neighbors". Each neighbor splits a signal, and the pattern observed matches the N+1 rule: the number of peaks observed is...
