## Abstract The structure of two premixed lean H~2~/O~2~/Ar flames, one uninhibited and the other inhibited by 3% of CF~3~H has been established at 4.6 kPa by using a mass spectrometric analyzer coupled with molecular beam sampling. The main effect of the CF~3~H addition concerns the formation of l
## Abstract Methyl groups bound to heterocyclic rings may, in certain circumstances, exchange hydrogen for deuterium. This exchange has been studied for alkyl or amino‐alkylpyrimidines in acid medium. The qualitative results obtained as a function of acidity, substituant location and temperature co
## Abstract La limite supérieure d'inflammation des mélanges (CH~4~, O~2~) de teneur comprise entre 6 et 66% de méthane a été mesurée dans des récipients de diamètres différents et aux températures comprises entre 500 et 800° C. Parmi les divers mélanges examinés, c'est le mélange CH~4~+8 O~2~ qui
**Hydrogen Transfer during Decompositions of Molecular Ions of Acetals Derived from Substituted Cyclopentanones and Cyclohexanones** The isomerisation process of ethylene‐acetal radical ions of low internal energy has been reinvestigated in more detail. The ring contraction of cyclohexane derivativ
