Summary A Cavity ring down spectrometer has been constructed to obtain high vibrational overtone spectra of molecules. Experiments at low pressures and low temperatures ( K) provide σ( ) values simulating atmospheric conditions. Low temperature ( K) quantum yields of chemical reactions are being obtained for vibrationally excited molecules under atmospheric conditions.
