Summary

This chapter deals with manipulating intermediates in the photochemical way. First, it focuses on intermediates and spin states that cannot be accessed thermally. Second, it explains the control of the reaction of intermediates by temperature, electron transfer, physical state and irradiation conditions. Radical ions are a quite active field of research, where the different results between the photochemical approach and other methods such as electrochemistry or chemical redox processes have been evidenced many times and the versatility of the former has been exploited to some degree. The chapter concludes with a discussion on the role of photochemistry that is more developed and promising for open-shell structures, such as radicals or radical ions. In these fields it would be advisable to test every new reaction by a photochemical method.
