%X A quantum electrodynamics (QED) correction surface for the simplest polyatomic and polyelectronic system H3+ is computed using an approximate procedure. This surface is used to calculate the shifts to vibration-rotation energy levels due to QED; such shifts have a magnitude of up to 0.25 cm−1 for vibrational levels up to 15 000 cm−1 and are expected to have an accuracy of about 0.02 cm−1. Combining our H3+ QED correction surface with existing highly accurate Born-Oppenheimer, relativistic, and adiabatic components suggests that deviations of the resulting ab initio energy levels from observed ones are largely due to nonadiabatic effects.
