SPECIFIC RATE CONSTANTS k(E,J) OF $NO_{2}$ FROM LINEWIDTH MEASUREMENTS USING OPTICAL DOUBLE-RESONANCE SPECTROSCOPY IN A FREE JET

Author Institution: Institute for Physical Chemistry, University of GoettingenLaser induced fluorescence detected optical V-type double resonance spectroscopy in a free jet has been employed to access and to assign rovibronic states of $NO_{2}$ above the dissociation threshold $E_{0}$. The measured homogeneous linewidths of isolated lines above the dissociation threshold have been converted into specific rate constants k(E,J). The rate constants, its fluctuations, and its dependence on E and J will be discussed in terms of statistical theories
