Book Description
Efforts focused on four activities related to the central objective of studying metal-containing clusters, HEDM molecules, and clusters of ceramic materials. Nineteen AFOSR supported papers were published on the following topics (including five journal cover articles) : 1) Development of high resolution (100 MHz), high sensitivity pulsed infrared cavity ringdown spectroscopy as a general tool for trace species characterization. 2) Infrared cavity ringdown system with medium (900 MHz) resolution constructed and operational. 3) IR studies of hydrogen bonding in water, methanol, ethanol, and butanol clusters carried out. 4) More difficult IR experiments on laser vaporized carbon and silicon carbide initiated.

Book Description
A high resolution infrared cavity ringdown laser absorption spectrometer has been developed to study proposed HEDM molecules and metal containing clusters. Using a novel tunable pulsed Alexandrite ring laser, we are able to generate tunable visible radiation with ca, 40 MHz bandwidth. This tunable visible light is downconverted to the infrared using stimulated Raman scattering in H2 and D2. With this system, tunable radiation from the UV to the far infrared can be generated with ca, 100 MHz bandwidth. We will test this system using our pulsed supersonic laser vaporization source to study both metal and carbon containing species. Infrared Cavity Ringdown Spectroscopy has also been used to study water clusters in both pulsed supersonic beams and pulsed discharged nozzles.

Book Description
Two new types of infrared spectrometers have been developed for the study of gas-phase cluster species. A tunable far-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.

Book Description
"Cavity-Enhanced Spectroscopy" discusses the use of optical resonators and lasers to make sensitive spectroscopic measurements. This volume is written by the researcchers who pioneered these methods. The book reviews both the theory and practice behind these spectroscopic tools and discusses the scientific discoveries uncovered by these techniques. It begins with a chapter on the use of optical resonators for frequency stabilization of lasers, which is followed by in-depth chapters discussing cavity ring-down spectroscopy, frequency-modulated, cavity-enhanced spectroscopy, intracavity spectroscopies, microresonators and cavity-enhanced comb filters. This book is aimed towards a reader with a background in optics and spectroscopy, but who is unfamiliar with the methods discussed in the book. *Practical implementation informationComprehensive review of cavity-enhanced methods*Written by the researchers who pioneered these spectroscopies*Discusses cavity-enhanced optical instrumentationReviews scientific discoveries unearthed using these methods
