It has been shown that each of the experimental techniques mentioned, LS, ARAS, and TOF (laser schlieren, atomic resonance absorption spectroscopy, time of flight), have a particularly important role to play in the elucidation of complex reaction schemes that are the rule in fossil fuel pyrolytic systems. Each of these three methods have been combined to produce an understanding of complicated problems that is greater than the sum of three individual efforts: to wit, ARAS can monitor the time history of H or D atom production in very dilute systems (LS and TOF cannot); LS can provide information about the enthalpy changes occurring (ARAS and TOF cannot); TOF can record the time histories of major and minor (not trace amounts) species that appear during the course of the reaction and also detect in some cases transient intermediates (e.g., phenyl or lack thereof, C/sub 4/H/sub 4/, C/sub 4/H/sub 3/, C/sub 7/H/sub 7/).
