In this video, I have explained how to calculate Nuclear Spins (I), Nuclear Configuration with Nuclear Shell Model, Filling of nuclear energy levels (ground sate/excited state) with protons and neutrons and to identify the responsive/NMR active isotopes based on spin. This is very important for NMR spectroscopy.
Four possibilities to calculate nuclear spin are explained as follows;
1) Even/Even. Nuclei containing even numbers of both protons and neutrons have I = 0 and therefore cannot undergo NMR.
2) Odd/Odd. Nuclei with odd numbers of both protons and neutrons have spin quantum numbers that are positive integers (1, 2, 3 ---).
3, 4) Odd/Even or Even/Odd. The remaining nuclei (odd/even and even/odd) all have spins that are half integral (1/2, 3/2, 5/2 -----
