Abstract:
The binary cluster of ammonia and methanol was studied using both laser MPI MS and the molecular beam technologies. Two serials of protonated cluster ions were measured:(CH3OH)n H+ and(CH3OH)n NH4+(1≤n≤14),which were produced from the proton transfer reactions in the binary clusters . The binary cluster of NH3 and CH3OD was also studied in the current work. The results showed that the transfer probability of the D in OD was several times larger than that of the H in CH3 . The calculation of binary cluster of CH3OH - NH3 with HF / STO - 3G and MP2 / 6 - 31G** basis sets,showed that the proton in OH was easier to transfer than that in CH3,as there was a barrier about 120kJ / mol for the proton in CH3 to transfer.

摘要:
用单脉冲激波管研究了全氟丙烯C3F6的分解。使用H2作为清扫剂。产物包括CH4、C2F4、CF3H和C2F3H,作为对断键反应过程的指示。C3F6的断键反应为 C3F6CF3+C2F3 (1) 得到其速率常数表达式为 k(C3F6CF3+C2F3)=10(17.4±0.2)exp-(355300±8360)/(RT)s-1 温度范围为1090K
