• Doublet state — In quantum mechanics, a doublet is a quantum state of a system with a spin of 1/2, such that there are two allowed values of the spin component, −1/2 and +1/2. Quantum systems with two possible states are sometimes called two level systems.… …   Wikipedia

• singlet state — the excited state occurring when one electron of a pair is excited to a higher energy level without changing its spin; it is unstable and can decay to either a ground state or a triplet state …   Medical dictionary
