Photoinduced reaction in the ion-molecule complex Mg+-nitromethane

(a) Photodissociation different mass spectra of the complex Mg+NO2 at 249 nm (upper panel) and 326 nm (lower panel). (b) Action spectrum of complex Mg+-NO2CH3. The vertical axis represents the total photofragment ion yield. The dotted line indicates the atomic transition of the Mg+ (32P ← 32S). The solid lines show the calculated excitation energies and oscillator strengths using the CIS method, by the structure of Mg+ bound to single O.
