Abstract

We use laser photoacoustic spectroscopy to obtain vibrational overtone spectra in the regions of four and five quanta of OH stretch (4νOH and 5νOH) for gas-phase methyl (MeOOH), ethyl (EtOOH), and tert-butyl hydroperoxide (t-BuOOH). Integrated cross sections for the main peak due to OH stretch excitation to 4νOH are similar for all three hydroperoxides (~ 2× 10-21 cm2 molecule-1 cm-1); cross sections for excitation to and ...
