Question: The Transitions were an R&B group hand-picked by a founding member of what two groups?
Sentence (from "Magnetic dipole transition"): They can be divided into two groups by the frequency at which they are observed: optical magnetic dipole transitions can occur at frequencies in the infrared, optical or ultraviolet between sublevels of two different electronic levels, while magnetic Resonance transitions can occur at microwave or radio frequencies between angular momentum sublevels within a single electronic level.
Relevant evidence: No
