Webb3 maj 2004 · The shape of the onset of the ionization efficiency curve shows that the adiabatic ionization potential of the radical is much lower than the vertical one, and … Webb3 maj 2004 · The shape of the onset of the ionization efficiency curve shows that the adiabatic ionization potential of the radical is much lower than the vertical one, and hence that the equilibrium configuration of the CF 3+ ion is very different from that of the molecule. Autoionization probably accounts for some of the ionization near threshold.

Webb14 maj 1995 · Moreover, the CF2 radical showed a different dependence on discharge duration to CF3 and CF radicals because of its longer lifetime. We have measured CF3, CF2 and CF radical densities in a RF discharge CHF3 plasma using infrared diode laser absorption spectroscopy and have observed the variation of radical densities with …
