Orientation effects in cross-beam ionization reactions between potassium and symmetric-top molecules
Symmetric-top molecules (CF$\sb3$Br, CF$\sb3$Cl, CF$\sb3$H and CH$\sb3$Br) in a seeded supersonic nozzle beam are orientation selected by a hexapole electric field, and collide at a right angle with fast (3-40 eV) potassium ...
I. Dissociation and aromatization of a semibenzene. Reactions of triphenylmethyl and methyl isobutyryl radicals. II. The chemistry of alpha- and beta- azo radicals
Part I. Semibenzene methyl 7,7-diphenyl-p-mentha-1(7),2,5-triene-8-carboxylate (1), which can be regarded as the para recombination product of triphenylmethyl and methyl isobutyryl radicals (5), affords exactly these ...
Thermochemical investigations of selected ternary strontium oxides and iridium-aluminum alloys by high temperature mass spectrometry
A quadrupole mass spectrometer system was redesigned with pulse counting electronics and a resistively heated, high-temperature furnace. This system was employed in Knudsen effusion experiments to investigate the high ...
