Principles of Nuclear Magnetic Resonance

Nuclear Spin and NMR-Active Nuclei

Description

Atomic nuclei have nuclear spin, which comes from the spins of their protons and neutrons. These particle spins are intrinsic angular momentum, and each electron, proton, and neutron has a spin value of 1/2. In nuclei, proton spins pair with other protons, and neutron spins pair with other neutrons. They do not pair with eac...

Transcript

Tutte le particelle atomiche possiedono un momento angolare intrinseco, o "spin". Elettroni, protoni e neutroni hanno ciascuno un valore di spin della metà.

A differenza degli elettroni, i protoni e i neutroni nei nuclei possono avere spin più elevati, ma i valori sono sempre semi-interi.

Tutte le particelle in un nucleo contribuis...
