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. date: 2014-03-10 official_url: http://dx.doi.org/10.1103/PhysRevA.89.032505 vfaculties: VMPS oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_source: WoS-Lite elements_id: 932194 doi: 10.1103/PhysRevA.89.032505 lyricists_name: Lodi, Lorenzo lyricists_name: Polyansky, Oleg lyricists_name: Tennyson, Jonathan lyricists_id: LLODI42 lyricists_id: OPOLY52 lyricists_id: JTENN43 full_text_status: public publication: Physical Review A volume: 89 article_number: 032505 issn: 1050-2947 citation: Lodi, L; Polyansky, OL; Tennyson, J; Alijah, A; Zobov, NF; (2014) QED correction for H-3(+).
