Ion dip spectroscopy: A new technique of multiphoton ionization spectroscopy applied to I/sub 2/

Journal Article · · Phys. Rev. Lett.; (United States)
A new method of high-resolution multiphoton spectroscopy based on competition between ionization and stimulated emission channels is described. It combines features of multiphoton photoionization with those of optical-optical double resonance. Results obtained for I/sub 2/ demonstrate the method and identify intermediate states involved in multiphoton photoionization. The method offers the potential for extremely sensitive sub-Doppler spectrosocpy of complex molecules.
