Transition Probabilities for LowLying Electronic States in C_{2}.
Abstract
The probabilities for nine electronic transitions among the lowlying excited states in the C2 molecule are calculated by the dipolemoment operator method and are given in the form of oscillator strength (or fvalues). The amount of hybridization in the 2 and 3 ,' molecular orbitals are calculated with a semiempirical method closely related to the Mulliken "magic formula." The agreement between the coefficient of hybridization thus obtained and those obtained with more refined calculations is satisfactory for the 2 +0(a) ground state (the only state that could be compared). The fvalues for the Swan, Deslandresd'Azambnia, Mulliken, FoxHerzberg, Phillips, and BallikRamsay transitions are calculated as I = 0.048 (experimental 0.034), j = 0.0650, f = 0.1025, f = 0.8184, f = 0.0027, and f = 0.0066, respectively. The fvalues for three additional, yet unknown, transitions between low4ying states are also reported.
