Notes:
The photoion–photoelectron coincidence (PIPECO) spectrum for (CO)+2 has been measured in the wavelength region of ∼600–1 000 A(ring). The lower limits for the bond dissociation energies of CO+ (X˜)⋅CO, CO+ (A˜)⋅CO, and CO+ (B˜)⋅CO are determined to be 29.8, 17, and 16 kcal/mol, respectively. Evidence supporting the existence of long-lived (CO)+2 states with dissociation lifetimes 〉40 μs at energies above the CO+ (X˜,v=0)+CO asymptote is found. The dissociative lifetimes of CO+ (A˜)⋅CO and CO+(B˜)⋅CO are estimated to be longer than 4 μs and 50 ns, respectively.
