高分辨二维自由基分子光谱的研究

In the study of this project, we combine optical heterodyne, magnetic rotation, field modulation, velocity modulation and concentration modulation spectroscopic techniques, to form various new laser spectroscopic techniques for detecting free radicals, ionic molecules and excited molecules with high sensitivity. Especially, the optical heterodyne - magnetic rotation - velocity modulation spectroscopic technique which was developed by our group to be used for the selective detection of ionic molecules with open shell. The spectra of some important free radicals and ionic molecules have bee obtained with high resolution using these techniques. The molecular constants of those species were refreshed with more accurate by fitting the model of Hamiltonians or by a b initio calculations. Some of them have been got for the first time. Meanwhile, we also applied the results of spectroscopic measurements to study the molecular dynamics of plasma discharges and to search the diagnostic methods of plasma systems. By way of carrying this project, it strengthens the relation and cooperation between our group and the some research group in the world. We have published 6 papers in the international journals and 8 papers in the domestic journals. Two graduate students for Ph.D. and four for master have got their academic degrees through this research project.
