摘要: Abstract We report vibrational predissociation spectra of the O n − , n = 3–10, 12 cluster ions in 700–2400 cm−1 range. The odd numbered clusters are consistent with their identification as 3 ⋅ ( 2 ) . even based on 4 core ion, where first two O2 molecules add to locations that individually break symmetry but together restore this symmetry. Beyond subsequent attachment yields bands close neutral O2, indicating special character is retained.
