Addition of a chiral shift reagent to a NMR sample often simplifies complex^1 H

Question

Addition of a chiral shift reagent to a NMR sample often simplifies complex^1 H NMR spectrum. How chiral shift reagent simplifies complex^1 H NMR spectrum? Un decoupled^13 C NMR and off-resonance^13 C NMR reveals the number of hydrogen(s) present on each carbon in a molecule by providing multiplicities of each carbon signal. Is there any other carbon NMR experiment(s) one can carry out that will provide the same information? If the above answer is yes, list the name the experiment(s) and elaborate how the technique(s) work.

Explanation / Answer

Answer:

Addition of chiral shift reagent, It becomes the Diastereomer and the splitiing pattern changes. Then it can easy to analyse spectra.
