A set of orbitals are said to be degenerate if they all have the same energy. This degeneracy can sometimes be lifted by external electric or magnetic fields.
(of a human or system) Having lost good or desirable qualities. (of an encoding or function) Having multiple domain elements correspond to one element of the range. The genetic code is degenerate because a single amino acid can be coded by one of several codons. (mathematics) A degenerate case is a limiting case in which a class of object changes its nature so as to belong to another, usually simpler, class. (physics) Having the same quantum energy level.
