复合物Mg^+-NCSCH_3光诱导反应

Photo-induced Reaction of the Complex Mg^+-NCSCH_3

观察了复合物Mg+鄄NCSCH3在230~440nm范围的光解离光谱.在此波段内的复合物光诱导产物的质谱显示,存在着非反应猝灭产物Mg+和反应产物Mg+NC、Mg+NCS.反应产物来源于S-C化学键的断裂.复合物的光解离光谱由两个对应于原子Mg+(32P←32S)跃迁的宽峰构成.由量化计算中的CIS方法所获得的吸收谱理论值与实验值吻合较好.

Photodissociation spectroscopy of the complex Mg+-NCSCH, in the spectral region of 230 similar to 440 nm was observed. Mass spectrometry of the products for photo-induced reaction in the complex Mg+-NCSCH3 exhibits the product Mg+ from nonreaction quenching and reactive products Mg+NC, Mg+NCS throughout the whole wavelength range. The reactive products originate from the breaking of S-C chemical bonds. The Photodissociation spectrum consists of two broad peaks corresponding to the atomic transition of Mg+(3(2)P <- 3(2)S). The absorption spectrum by using CIS method of quantum chemical calculation agrees with the experimental spectrum.
