【摘要】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.更多还原

【Abstract】 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+(32P←32S). The absorption spectrum by using CIS method of quantum chemistry calculation agrees with the experimental spectrum.更多还原
