A mass spectrometric investigation of the thermal decomposition of acetone in a quartz reactor has been undertaken, in the 40–200 microns pressure range, in the absence of a carrier gas. The analysis of the results shows that below 400°C acetone u

The thermal behavior of acetaldehyde, at pressures of the order of 100 microns, has been investigated, up to 750°C, in a quartz reactor connected to a TOF Bendix mass spectrometer. In those conditions, no methane formation has been observed. Two imp

The EPR spectra of N-substituted benzyl N-t-butyl nitroxides show a significant dependence of the β-CH2 proton hyperfine coupling constants on the position and the number of phenyl substituents. This behaviour may be explained by simple steric consi

Different ways of approach have been proposed for the study of bond breakage probabilities under electron impact. The most interesting ones are calculation of stabilities, rupture coefficient and «indices de fragmentation», as proposed by Pahl, Via
