We have developed a spectroscopy technique to measure local emission spectra of diatomic molecules by using the Zeeman effect in plasmas with the external magnetic field. In order to develop this technique, two research topics were investigated :(1) Establishment of a method to evaluate the spectral line shapes of diatomic molecules in plasmas with the external magnetic field,(2) Application of the spectroscopy technique to a magnetic confinement fusion experimental device. Topic(1) was accomplished as expected in the research proposal. For topic(2), the spectra were measured, but we have not succeeded to resolve the magnitudes of the Zeeman effect because of the lack of the wavelength resolution. As an additional achievement, the ro-vibrational molecular constants of diatomic molecules which contains hydrogen isotopes were evaluated.

利用外加磁场下等离子体中的塞曼效应，我们发展了一种测量双原子分子局域发射光谱的光谱技术。为了发展这一技术，我们开展了两个方面的研究工作：（1）建立一种测量外磁场作用下等离子体中双原子分子谱线形状的方法;（2）将光谱技术应用于磁约束聚变实验装置。课题（1）的研究达到了研究方案的预期目标。对于主题（2），测量了光谱，但由于缺乏波长分辨率，我们还没有成功地解决塞曼效应的大小。作为补充，计算了含氢同位素的双原子分子的振转分子常数。
