    Dr. Masiello's research interest is focused on utilizing spectroscopic techniques to characterize, detect, and quantify gas phase chemicals.  The characterization of chemicals is accomplished through the analysis of high resolution (~0.001 cm-1) infrared and Raman spectra.  This analysis yields important information regarding molecular structural parameters such as precise bond lengths and bond angles, as well as yielding information regarding the bonding energy between atoms in a molecule.  Chemical concentrations are determined through analysis of low resolution (~0.125 cm-1) infrared spectra and has been used to 1) validate chemical agent detectors, 2) determine temperature dependent vapor pressure and enthalpy of vaporization parameters, as well as 3) determine Henry's Law constants.  Addition research interests involve the use of cavity enhanced techniques such as cavity ringdown spectroscopy and integrated cavity output spectroscopy to detect chemicals at trace levels. Current projects involve investigating reaction rates of ozone with anthropogenically produced carbon compounds as well as developing methods that increase the precision to which chemical concentrations are reported.
