| 摘 要： | 观察了复合物Mg+-NCSCH3在230~440 nm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.

| Abstract: | Photodissociation spectroscopy of the complex Mg+-NCSCH3 in the spectral region of 230~440 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+(32P←32S). The absorption spectrum by using CIS method of quantum chemical calculation agrees with the experimental spectrum. |
