英文摘要: The energy transfer processes between (CO)-C-12(A(1)Pi) and (CO)-C-13(X (1)Sigma(+)) were studied at 77 K by using the technique of two-color resonance enhanced multiphoton ionization spectroscopy. In a static cell with a mixture of 0.92 (CO)-C-13 + 0.08 (CO)-C-12, (CO)-C-12 molecules were populated to the A state by 2-photon excitation using an UV dye laser. The (CO)-C-13(A) resulted from the collision E-E energy transfer were detected by CO(A)-> CO(B)-> CO+ (X) 2-step ionization using a visible dye laser. The energy transfer processes were found to be very fast with total cross sections of 114 +/- 42, 22 +/- 4, 17 +/- 6 angstrom(2) for (CO)-C-12(A) V=1,2,3 respectively. We found that for different vibrational channels, cross section decreases with increasing energy mismatch Delta E. Another interesting result is that, for the Lambda doublet, the production of Pi(+) is always larger than that of Pi(-). The formation of an intermediate exciplex [OCCO]* is proposed to explain the experimental results.
