Benzeneazodiphenylamine (4-phenylazodiphenylamine) [28110-26-1] M 273.3, m 82, pK 1.52. Purified by chromatography on neutral alumina using anhydrous C6H6 with 1% anhydrous MeOH. The major component, which gave a stationary band, was cut out and eluted with EtOH or MeOH. [Hogfeldt and Bigeleisen J Am Chem Soc 82 15 I960.] Crystd from pet ether or EtOH. See Sudan I.

Der EinfluB des Isotopieeffektes auf die Geschwindigkeitskonstante lafit sich nach Bigeleisen (21) und Pitzer (152a) berechnen. 

Aus theoretischen Griinden kann ein Isotopieeffekt nur dann beobachtet werden, wenn das markierte Atom am geschwindigkeits-bestimmenden Reaktionsschritt mitbeteiligt ist [Ropp, Weinberger und Neville (175), Bigeleisen, Bothner-By und Friedman (23)].

Both values were obtained by photochlorination of H2, HT and HD. Bigeleisen et al. also showed that k22jk23 < 0.05 at 298° by searching for HD in the photo-... 

Since the discovery of the deuterium isotope in 1931 [44], chemists have long recognized that kinetic deuterium isotope effects could be employed as an indicator for reaction mechanism. However, the development of a mechanism is predicated upon analysis of the kinetic isotope effect within the context of a theoretical model. Thus, it was in 1946 that Bigeleisen advanced a theory for the relative reaction velocities of isotopic molecules that was based on the theory of absolute rate —that is, transition state theory as formulated by Eyring as well as Evans and Polanyi in 1935 [44,45]. The rate expression for reaction is given by...
