Au(111) or similar noble metal surfaces feature Tamm-Shockley surface statesthat are known to possess considerable spin-orbit splitting of the Rashba typeof order $\Delta=0.1$ eV. When interacting with an electromagnetic field suchstates are expected to have resonances when the frequency of the field is nearthe energy of the spin-orbit splitting $\Delta$. These resonances originate inthe intersubband transitions between spin-split subbands. Such resonances canbe observed in the frequency dependence of the surface impedance. Plasmons inthin metal films are gapless and can be strongly affected by these spinresonances, acquiring significant modification of the spectrum when itintersects the $\omega=\Delta$ line. Finally, an interesting demonstration ofthe intersubband resonances can be obtained when metal films are coated withionic dielectrics that have a frequency of longitudinal/transverse opticalphonons above/below $\Delta$. The dielectric function between the two opticalphonon frequencies is negative which forbids propagation of conventionalplasmon-polaritons. However, the presence of spin-orbit-split surface statesallows plasmon-polaritons to exist in this otherwise forbidden range offrequencies.
