[Abstract]:In the field of molecular spectroscopy, isotope rotational spectroscopy instead of precise molecular structure technology is derived based on other technical difficult to match. By fitting and analysis by molecular spectroscopy of molecular rotation capture hyperfine rotational transition, rotational spectroscopy can obtain a laboratory of molecular geometry and electronic structure of the most accurate. It not only can provide absolute standards for quantum chemistry calculation, but also provides new challenges and opportunities for the laser ablation. And a high voltage discharge auxiliary technique for sample preparation is sample preparation system of molecular rotation spectrometer based on molecular manufacturing can be used to, unstable in air ions, free radicals, in order to capture the hyperfine spectrum spectrometer for them. In order to remote sensing of atmospheric composition, molecular spectroscopy provides space detection, has important application value of the universe and the origin of life research field The data in this paper. Sample preparation system of molecular rotation spectrometer as the research object, focuses on the research of key technology assisted sample preparation system with laser ablation of high voltage discharge. Firstly introduced the related theory of molecular rotation spectrometer sample preparation system components, then focus on the sample preparation system of molecular rotation spectrometer to build, and to study the vacuum technology, anti magnetic technology, gas rotational temperature control technology, improve the instrument sensitivity of multi pulse free induction decay technique. Finally introduces the use of laser ablation and auxiliary sample manufacturing technology of copper organic compounds CuCH_3, CuCN and CuCCH, and the spectral data obtained through the analysis of the feasibility of assisted sample preparation system laser ablation and high voltage discharge and improve unstable molecules to yield excellent sample preparation ability is verified by experiment.
