Spectroscopic Notation - Pennsylvania State University
personal.psu.eduSimilarly, spectroscopic notation just gives one number for the sum of all the electron spins, i.e., S⃗ = ∑ i ⃗si (12:03) Since electrons can only have spin-up or spin-down, a 2-electron system can only have S = 0 or S = 1. For light elements, \LS coupling" is a good rule; this simply means that the total angular momentum of an atom is ...

www.egr.msu.edusynchronous speed no power is delivered. The reason why there is not power is because the difference between the synchronous speed and the operating speed is zero. But if a motor is driven at a higher speed than the synchronous speed, the torque will be negative and start acting as a generator rather than a motor.
