摘要
在星际介质中发生的数以百万计的反应所产生的产物的可靠性取决于对速率常数的分析。目前的研究是利用b3lyp6 -311++ G (d, p)的基础集,利用密度泛函数理论(DFT)进行的化学建模研究。醋酸甲酯在星际介质中的水解是用量子化学参数EHOMO(最高占据分子轨道能量)、ELUMO (ISM条件下星际化学醋酸甲酯的低可能反应位点)、局部反应描述符Fukui函数、NBO、和MEP进行了深入分析。热化学研究有助于改进化学反应机理,计算被研究物质的速率常数有助于分析被研究反应的可行性。
Quantum Chemical Reactivity Investigation on ism Methyl Acetate Through DFT Studies
The reliability of the product that will arise from the millions of reactions that are taking place in interstellar medium is dependent on the analysis of the rate constant. The current investigation is a chemical modelling research performed with Density Functional Theory (DFT) studies utilizing a foundation set of B3LYP 6-311++ G (d, p). The hydrolysis of methyl acetate in the interstellar medium is described using the quantum chemical parameters EHOMO (highest occupied molecular orbital energy), ELUMO (lowe probable reactive sites of the interstellar chemical methyl acetate in the ISM condition, the local reactivity descriptors Fukui function, NBO, and MEP were analysed in depth. The thermo chemical investigation contributed to the improvement of the chemical reaction mechanism and the calculation of the rate constant of the species under investigation results in the analysis of feasibility of the reaction under study.
