CHF2Cl and CH3CF2Cl detection by coherent anti-Stokes Raman scattering and photoacoustic Raman spectroscopy Academic Article uri icon

abstract

  • The coherent anti-Stokes Raman scattering (CARS) and photoacoustic Raman spectroscopy (PARS) spectra of gaseous CHF2Cl and CH3CF2Cl in the 3000 cm-1 region are reported for the first time. Several vibrational bands are observed related to C− H stretch fundamentals of CHF2Cl isotopomers, and to CH3 stretches and the first overtone of CH3 deformation of CH3CF2Cl. The simultaneous detection of CARS/PARS signals aids the assignment of the isotopomer bands. Both methods are appropriate for detection of these compounds and can be applied in chemical dynamics studies.
