Emission spectra from collisions of 8keV He+ and H2+ with neutral naphthalene, benzene, acetylene and methane were acquired over 190–1020nm on a modified double-focusing mass spectrometer. The bands, emission intensities and the minimum excitation energy to produce the observed transitions (Emin) were compared for the two projectile ions. Emin values were the same for both projectiles but the emission...
The heat of formation of ClSO + , 802 ± 1 kJ mol -1 at 0 K, has been obtained by the dissociative photoionization of supersonically cooled thionyl chloride, Cl 2 SO. Threshold photoelectron photoion coincidence spectroscopy was used to obtain the appearance energy from the cross-over point in the breakdown diagram for the dissociation. Also measured was the adiabatic...
