a) 436 HZ
Interpretation:
Many nuclei have spin and all nuclei are electrically charged. If an external magnetic field is applied, an energy transfer is possible between the ground energy to a higher energy level.
Concept introduction:
The exact frequency necessary for resonance depends both on the strength of the external magnetic field, the identity of the nucleus, and the electronic environment of the nucleus. If a very strong magnetic field is applied, the energy difference between the two spin states is larger and higher-frequency (higher-energy) radiation is required for a spin-flip. If a weaker magnetic field is applied, less energy is required to effect the transition between nuclear spin states.
b) 956 HZ
