Kinetic energy release and mean life time of metastable ions produced from C3H3N

Mapping the complex metastable fragmentation pathways of excited 3-aminophenol+

“…Band J in Fig. 4 [39]. Głuch et al [39] showed that the time dependence of double hydrogen loss from C2H2 + fragments of suggests H2 production in stable and unstable states with respect to subsequent dissociation.…”

“…4 [39]. Głuch et al [39] showed that the time dependence of double hydrogen loss from C2H2 + fragments of suggests H2 production in stable and unstable states with respect to subsequent dissociation. Other metastable dissociative ionization expriments that provide evidence to distinguish between the production of H2 or of two separate hydrogens include Feil et al's [40] and Roithová et al's [41] observations of H2 loss from doubly-charged toluene.…”

Electron impact ionization of acetaldehyde

“…In our laboratory observations of metastable fragmentation reactions of ions produced by electron impact of molecules play a special role [3][4][5][6][7][8][9]. Just absence of metastable fragmentation reactions of acetaldehyde ions was for us direct encouragement for the investigations presented here.…”

Resonant Auger electron–photoion coincidence study of the fragmentation dynamics of an acrylonitrile molecule

“…In the case of solid acrylonitrile the non-radiative (electronic) decay channels at the nitrogen K-edge have been studied by resonant Auger electron spectroscopy (RAES) [17] and for the gas-phase acrylonitrile the mass spectrometric investigation results of ionization and appearance energies for all detected cations have been published [18]. Recently, the kinetic energy release (KER) distribution for the metastable decay reactions of ions formed by electron impact on acrylonitrile has been reported [19]. The possible molecular and radical elimination channels in acrylonitrile photodissociation in the vacuumultraviolet region have been investigated by many different experimental techniques-flash photolysis-kinetic absorption spectroscopy [20], laser-induced fluorescence spectroscopy (LIF) [21], transient frequency-modulation spectroscopy [22], photofragment translational spectroscopy (PTS) [23] and timeresolved Fourier transform infrared emission spectroscopy [24].…”
