Abstract:

Two new types of infrared spectrometers have been developed for the study of gas-phase cluster species. A tunable for-infrared FIR laser was combined with an apparatus for producing planar supersonic beams of laser vaporized clusters, and used in the measurement of the 64.1 cm-1 bending vibration of C sub 3. A mid-IR diode laser system was constructed with a similar cluster source, and used in studies of the C sub 4, C sub 5, C sub 7, and C sub 9 clusters. Structures and internal dynamics of the clusters were determined. Extensions to metal cluster systems are currently underway. A new type of spectrometer was developed for measuring electronic spectra of supersonic metal clusters. Cavity Ringdown Laser Absorption Spectroscopy CRLAS was utilized in a study of the Cu sub 3 cluster in the initial application of the method.
