中文摘要：

研究了230～440 nm波段复合物Mg^＋-S2（CH3）2的单光子光诱导反应.复合物光诱导产物的质谱揭示,存在着非反应猝灭产物Mg^＋和反应产物Mg^＋SCH3.复合物的光解离光谱由三个对应于离子Mg^＋（32P←32S）跃迁的宽谱峰构成.用量化计算中的CIS方法所得的吸收谱理论值与实验值吻合较好.

英文摘要：

The single photon induced reaction of complex Mg^＋-S2（CH3）2 was studied in the spectral region of 230-440 nm. The mass spectrometry of the photo-induced reaction of the complex Mg^＋-S2（CH3）2 exhibits the existence of the products Mg^＋ and Mg^＋SCH3 throughout the whole wavelength range. The photodissociation spectrum consists of three broad peaks corresponding to the atomic transition of Mg^＋（3^2P←3^2S）. The absorption spectrum by using CIS method of quantum chemistry calculation agrees with the experimental spectrum.
