复合物Mg^+-S_2(CH_3)_2的光诱导反应

Photo-induced Reaction of the Complex Mg^+-S_2(CH_3)_2

研究了230￣440nm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.

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.
