WebVarious amounts of internal energy were deposited into the ions upon CAD by variation of the collision energy and collision gas pressure. In addition to isobutane, deuterated isobutane C4D10 also was used as reagent gas in chemical ionization. The daughter ions [M + H - C2H4]+ and [M + H − 2C2H4]+ dominate the CAD spectra. WebThe photolysis of n-C4D10 has been investigated with 8.4 eV and 10.0 eV photons, using HI to scavenge free radicals through the reaction: R d + HI → R d H + I (where R d is a fully deuterated alkyl or alkenyl radical). From the results of such experiments, the quantum yields of the molecular and radical products are obtained over a pressure range from 3 to …
