摘要: With the aid of a molecular resonance fluorescence technique, which utilizes optical pumping from v=1 level ground state CO by A1Π‐X1Σ+ radiation, we have investigated efficiency E‐V transfer O(1D) to CO. is generated at known rate O2 photodissociation 1470 A in an intermittent mode, and small modulation fluorescent signal associated with CO(v=1) above normal thermal background interpreted terms efficiency. The lifetime this system determined mainly trapping their fundamental band, found be up ten times longer than natural radiative lifetime. For CO, (40 ± 8)% energy converted into vibrational energy. By observing effect N2 on intensity lifetime, it possible obtain for O(1D)–N2 relative that O(1D)–CO. results indicate (83 10)% ...
