Hyperfine electron affinities of molecular oxygen

Theoretical hyperfine valence electron affinities of O2 are identified in thermal, electron impact, photon and electrochemical data. The ranges of the 162 values are: (eV) 72-[X2Π, 1.030(2) to 1.100(2): C2Π, 0.410(2) to 0.480(2); d4Π, 0.228 to 0.342; f4Π, 0.128 to 0.242]; 36-[b4Δ, 0.685 to 0.917; A2Δ, 0.541 to 0.611]; 54-[a4Σ, 0.920 to 0.990; e4Σ, 0.215 to 0.285; b4Σ, 0.710 to 0.780; B2Σ, 0.495 to 0.545; D2Σ, 0.395 to 0.445; E2Σ, 0.335 to 0.385]. These demonstrate the existence of 162 bonding and 162 antibonding hyperfine states dissociating to the lowest limits. Multiple long range Efimov-like states with electron affinities less than 0.10 eV are also identified.
