红外-紫外光学双共振研究C6F6的振动弛豫
IR-UV double resonance studies of vibrational relaxation of hexafluorobenzene
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)×10~3sec~(-1)Torr~(-1),Koo2=(7.1±0.8)×10~3sec~(-1)Torr~(-1),Kxe=(2.9±0.47)×10~4sec~(-1)Torr~(-1).C6F6的自弛豫速率常数的测定值K(C6F6)=(0.4±0.15)×10~6sec~(-1)Torr~(-1),与Lambert-Salter经验关系值相当符合.
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.
