analysis of this value suggests that the average energy transferred during collisions between Ar and the excited intermediate is DeltaE = -360(-160) (+90) cm(-1). Over 300-800 K, the high-pressure limit is predicted to be k(infinity) = 2.2 x 10(-10) (T/300)(0.24) cm(3) molecule(-1) s(-1). Doublet and quartet adducts between S and NO were characterized via CBS-QB3 theory. The kinetic data can be rationalized
在60-800 mbar的压力下,通过300-810 K的激光光解共振荧光技术研究了S((3)P(J))与NO((2)Pi)在Ar浴气体中的反应。观察到的二阶速率常数接近低压极限。拟合Troe的形式主义进行实验,估计F(cent)= 0.78 exp(-T / 7445)和k(无穷大),随后得出k(0)=(6.2 +/- 0.6)x 10(-33) exp(+(940 +/- 40)/ T)cm(6)分子(-2)s(-1)。误差极限为+/- 25%。此值的理论分析表明,在Ar与受激中间体之间的碰撞过程中转移的平均能量为DeltaE = -360(-160)(+90)cm(-1)。在300-800 K以上时,高压极限预计为k(无穷大)= 2.2 x 10(-10)(T / 300)(0.24)cm(3)分子(-1)s(-1)。通过
CBS-QB3理论表征了S和NO之间的二重态和四重态加合物。可
