A brief summary of collective mode excitations that can exist in singlet superconductors with irreducible representation L is given. Such excitations may be classified as the coupled excitations of the charge density ρ and the phase ϕ of the order parameter, or of the amplitude Δ of order parameter. Each of these classes may be further characterized in the long wavelength limit by the irreducible representation ℓ of the excitation, which may or may not be the same as the ground state L.
