摘要
在230～440nm波段，研究了复合物Mg+－S2(CH3)2的光解离光谱。此波段内的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。反应产物来源于Mg+离子插入S－S化学键，导致复合物解离的过程。复合物的光解离光谱由三个对应于离子Mg+(32P←32S)跃迁的谱峰构成。由量化计算中的CIS方法所获得的吸收谱理论值与实验吻合地较好。
Abstract
Photodissociation spectra of the complex Mg+-S2(CH3)2 in the spectral region of 230～440 nm was observed. Mass spectrometry of the products for photo-induced reaction in the complex Mg+-S2(CH3)2 exhibits the product Mg+ from nonreaction quenching and reactive products Mg+-SCH3 throughout the whole wavelength range. The reactive products originate from the rupture of S-S chemical bonds. The photo dissociation spectrum consists of two broad peaks corresponding to the atomic transition of Mg+(32P←32S). The absorption spectrum by CIS method of quantum chemistry calculation agrees with the experimental spectrum.
