We are vigorously pursuing extension of cavity ringdown laser absorption spectroscopy into the infrared $region.a,b$ With medium resolution $(-1000MHz)$, we have measured spectra of $H2O,D2O,CH3OH,CH3CH2OH$, and $CH3(CH2)3OH$ 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 cavity ringdown experiments are also being pursued using a novel Alexandrite based laser system.
