Of greater interest is the occurrence of the explosion region at low pressures [9—12] where, just outside the explosion limit, the rate of 

With the possible exception of those on the third limit, all the kinetic investigations of the above type have been carried out under essentially isothermal conditions, often with rather low concentrations of chain centres. With such low concentrations of chain centres it is usually necessary only to consider reactions of free radicals with stable molecules. 

An intermediate field of study, between the earlier investigations and the flame and shock tube work, is that of the slow reaction and explosion limits in vessels of very low chain breaking efficiency. Here, in contrast with vessels of higher efficiency, radical—radical reactions do begin to be important even in determining limit conditions and slow reaction rates. Into this class fall a number of extensive investigations of the reaction in boric acid coated vessels, which will be discussed. These investigations provide a valuable link between the other two areas of study.
