Abstract
We are vigorously pursuing extension of cavity ringdown laser absorption spectroscopy into the infrared $region.^{a,b}$ With medium resolution $(^{-}1000 MHz)$, we have measured spectra of $H_{2}O, D_{2}O, CH_{3}OH, CH_{3}CH_{2}OH$, and $CH_{3}(CH_{2})_{3}OH$ clusters in the spectral region between 2.8 and 6 microns. By employing a laser vaporization/supersonic molecular beam source, we have also studied carbon clusters in this spectral region. High resolution $(<100 MHz)$ cavity ringdown experiments are also being pursued using a novel Alexandrite based laser system.
