A calculation of the optical properties of electronic bubbles in liquid helium is presented. Making use of the measured well depth and surface tension, we have computed the electronic states as a function of bubble size and have calculated the configuration coordinate diagrams, transition energies, oscillator strengths, lifetimes, cross sections, line shapes, linewidths, and estimated the magnitude of the static Jahn-Teller effect in an excited state. The dependence on pressure is considered for some of these quantities from 0-20 atm.
