Expert Solution
Step 1
  • C13-NMR helps in deduction of chemical formula/ structure for compounds by deducing the signals of C13.
  • In this C13-NMR, when the nuclei in precessional motion interacts with the that radiofrequency pulse, then it feel a torque for its spin change, when is precessional frequency becomes equal to radiofrequency and the nuclie will go to higher spin energy state resulting in C13-NMR.
