In quantum mechanics, a triplet is a quantum state of a system with a spin of quantum number s=1, such that there are three allowed values of the spin component, ms = −1, 0, and +1. Spin, in the context of quantum mechanics, is not a mechanical rotation but a more abstract concept that characterizes a particle's intrinsic angular momentum. It is particularly important for systems at atomic length scales, such as individual atoms, protons, or electrons.
