【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.更多还原
