| 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 showedthat 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. |
