“…The simplest explanation for the consumption of more than half the atomic nitrogen with no product formation in the presence of methyl alcohol is the reaction -where the alcohol is an efficient third body. According to Geib (12) there is evidence of catalytic recombination of hydrogen atoms in the presence of methyl alcohol. -Alternatively the "wastage" could result from intermediate formation of NO or S O H .…”

The reaction of active nitrogen with methanol has been investigated a t several temperatures in the range 30 to 48OoC using a fast-flow system. The only condensable products found in appreciable amou~lts were water and hydrogen cyanide. The overall activation energy is 3.0 and 3.2 kcal/mole and the steric factors 1.3X10-3 and 2.1X10-3 for streamline and turbulent flow respectively. I t is postulated that the mechanism consists of the initial formation of a collision complex, [NCH30H], which breaks down to two fragments, S C H 3 and OH, from which the two condensable products are formed, NCH3 -+ H C N + 2H or Hz &qttack of the r~letharlol n~olecules b y hydrogen atoms resulting from the main reaction occurs t o a lesser extent and is responsible for the production of small quantities of methane, carbon monoxide, and additional water. INTRODUCTIOS

“…It has been suggested by Herzberg [12] that the source of the continuous absorption in the spectrum of H2S is due to the primary dissociation H2S + hv + H + HS (5) and that the formation of the observed S atoms is due to the occurrence of the secondary reaction (3). Porter [13] and Ramsay [14] detected and analyzed the absorption spectrum of the HS radicals in the flash photolysis of H2S and on the basis of the pressure and temperature effects on the quantum yield of H 2 formation, they suggested a complete mechanism consisting of reaction (5) followed by reactions (2)- (4).…”

“…A similar technique was used by Farkas [4] for the studies of the thermal conversion of para to ortho hydrogen and of the exchange reactions with deuterium. This early period was reviewed by Geib in 1936 [5].…”
