【摘要】 分子离子H2D+在天体物理和天体化学研究中有重要意义,但在实验研究中不可避免混入D+2从而对实验结果产生影响.本文采取产物对比与分析的方法,将离子源中两种离子的比例实际测量出来,从而能较为准确地研究H2D+的结构和性质.将实验测量的结果与理论推算进行比较,得到了相对较好的结果.本文所采用的方法将对类似的研究提供有益的借鉴和启发.更多还原

【Abstract】 The molecular ion H2D+is important in astrophysics and astrochemistry study,but it inevitably mixed with D+2in the experimental detection and measurement,the experimental results will be influenced.This paper adopts the method of comparison and analysis of coulomb explosion products,the proportion of the two kinds of ions is obtained in HF ion source,which can reach more accurately study on structure and properties of H2D+.The experiment results and theoretical calculation were compared and get relatively good results.This method will provide a useful reference and inspiration for similar research.更多还原
