Question

Nuclear spin dependence on masss no, and atomic no

Answer 1

Answer:

nucleus, it will have an integer spin (i.e. 1, 2, 3) If the sum of the number of neutrons and the number of protons is odd number, the nucleus will have a half-integer spin (i.e. 1/2, 3/2, 5/2).

These rules can be summarized in terms of atomic mass and atomic number as shown below

Answer 2

Explanation:

he chemical shift of carbons is caused by the same phenomenon as the chemical shift of hydrogens, i.e., the electrons in the molecule generate small magnetic fields that affect the net field experienced by each carbon nucleus. ... Carbon-12 atoms do not have a nuclear spin, and hence don't show up in the NMR
