Question

A nucleus with an ________ atomic number or an ________ mass number has a nuclear spin that can be observed by the nmr spectrometer. a. odd; even b. odd; odd c. even; even d. even; odd

Answer 1

A nucleus with an odd atomic number or an odd mass number has a nuclear spin that can be observed by the nmr spectrometer.

Where there are several nucleons in the nucleus, their spins are coupled to cancel each other out. On the other hand, a nucleus with just an odd count of nucleons has an ongoing overall spin. This is why NMR uses atoms like the $H^{1}$ and the $C^{13}$.

NMR can not measure nuclei where quantum spin is 0 since it requires the presence of this magnetic moment. Nearly all isotopes with an even count of protons but instead neutrons lack a magnetic moment, making them impossible to detect with NMR.

Nuclear spin refers to the magnetic characteristics of hydrogen nuclei (protons). They act like small, vector-represented rotating magnets. Net magnetization, also known as macroscopic magnetization, would be the total of all the small magnetic fields produced by each spin. These vectors' directions are often distributed at random.

Therefore, a nucleus with an odd atomic number or an odd mass number has a nuclear spin that can be observed by the nmr spectrometer.
