Spectroscopic Studies of van-der Waals Molecules under Extremely High-electric Field

该项目最初是为了在强电领域研究氨的隧道动力学。我们看到，我们的研究是从我们的原始提案中提取出来的，是1999年变革性人员的结果。该项目的焦点已经转移到弱离子化等离子体中的分子动力学。在这份报告中，对分子动力学在强电场中的评论，作为良好的结果，D3+（/）3 D D 3在弱电离等离子体中将被呈现。在资助期的第一年，我们完成了为一代超声波自由喷气式汽油的主室的建造。T. T. Amano has tested the performance of the system by studying the near infrared？D11？D1？D13？D1？D22？D2？D1？D2？D1？D2？D1一个高电压（50千伏）直流电源供应被用于一代的高电场。1999年，Man-Chor Chan在1999年的收容所中进行了进一步的试验。在过去的筹资期间，我们已经研究了氢等离子体的分子动力学研究。Our observation has led to a better understanding of the chemManagement in this system， such as dissociative recombination reaction of H·D3（/）3·D3 （and D·D3·（/）3·D3） and the concentrations of D·D2·D3·（/）5·D3。This information will be useful in our future search for the spectrum of H-D3+（/）5-D3。D23-D2 spectrum will also he important in verifying our interpretation of the linewidths and lineshapes。

The project was initially designed to study the tunneling dynamics of ammonia in strong electric field. It is seen that our studies have deviated from our original proposal as a result of changing personnel in 1999. The focus of the project has shifted to molecular dynamics in weakly ionized plasma. In this report, a review of molecular dynamics in strong electric field as well as the results of the formation mechanism of DィイD3+(/)3ィエD3 in weakly ionized plasma will be presented. In the first year of the funding period, we completed the construction of the primary chamber for the generation of supersonic free jet of gas. T. Amano has tested the performance of the system by studying the near infrared band ィイD11ィエD1SuィイD1+ィエD1׬ ィイD13ィエD1SgィイD1-ィエD1 of OィイD22ィエD2. A high voltage (50 kV) DC power supply was purchased for the generation of high electric fields. The proposed experiments proceeded no further after the resignation of Man-Chor Chan in 1999. In the past funding period, we have pursued molecular dynamic studies of hydrogen plasmas. Our observation has led to a better understanding of the chemistry in this system, such as dissociative recombination reaction of HィイD3+(/)3ィエD3 (and DィイD3+(/)3ィエD3) and the concentrations of DィイD23ィエD2 and DィイD3+(/)5ィエD3. This information will be useful in our future search for the spectrum of HィイD3+(/)5ィエD3 (and DィイD3+(/)5ィエD3). Further systematic investigation of the DィイD23ィエD2 spectrum will also he important in verifying our interpretation of the linewidths and lineshapes.
