FELIX is also shown schematically in Fig. 1.19. This method of infrared resonance enhanced multiphoton ionization (IR-REMPI) has been successfully applied to study fullerenes, metal carbide, metal oxide, and metal nitride clusters [126,128-130] as well as metal-adsorbate complexes [131]. [Pg.26]

In addition to laser fluorescence excitation, several other laser spectroscopic methods have been found to be useful for the state-selective and sensitive detection of products of reactive collisions resonance-enhanced multiphoton ionization [58], coherent anti-Stokes Raman scattering [M], bolometric detection with laser excitation [30], and direct infrared absorption [7]. Several additional laser techniques have been developed for use in spectroscopic studies or for diagnostics in reacting systems. Of these, four-wave mixing [ ] is applicable to studies of reaction dynamics although it does have a somewhat lower sensitivity than the techniques mentioned above. [Pg.2082]

Infrared diode laser absorption spectroscopy has been employed to detect ground-state SiH2 and allowed the first observation of its high-resolution IR spectrum by Yamada and coworkers in 1989 . State-selective multiphoton IR excitation of SiH2 has been examined computationally . The resonance-enhanced multiphoton ionization (REMPI) spectrum of SiH2 was observed for the first time by Robertson and Rossi and was employed to measure the SiH2 sticking coefficient on a silicon surface . ...
