WebIn 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.
