【摘要】 采用红外-紫外光学双共振技术,首次测得六种碰撞伙伴对振动激发C₆F₆分子的脱活速率常数,例如,Ko₂=（8.8±0.4）×10³sec^-1Torr^-1,Koo₂=（7.1±0.8）×10³sec^-1Torr^-1,K_xe=（2.9±0.47）×10⁴sec^-1Torr^-1.C₆F₆的自弛豫速率常数的测定值K_C6F6=（0.4±0.15）×10⁶sec^-1Torr^-1,与Lambert-Salter经验关系值相当符合.更多还原

【Abstract】 The deactivation rate constants by 6 different collision partners of vibrationally excited C6F6 have been measured for the first time using an IR-UV double resonance technique, for example, KO2= (8.8±0.4) ×103 sec-1.Torr-1, KCO22= (7.1 ±0.8) ×103 sec-1 · Torr-1 and KXe = (2.9± 0.47) × 104 sec-1 · Torr-1. The measured value of KC6F6 = (0.4±0.15)×106seo-1·Torr-1 agrees well with the Lambert-Salter empirical correlation.更多还原
