“…It was observed that for the reaction of both tetraalkylleads with ozone there was an excess consumption of ozone, with a stoichiometry in the region of 4:1. By analogy with similar observations with the alkene-ozone reaction, it is possible to interpret this stoichiometry as resulting from the reaction of primary reaction products with ozone (20).…”

“…The possible routes of the Os-propylene reaction are shown in Figure 3. Latest evidence seems to suggest that the Criegee paths are favored over the hydrogen abstraction paths for the lower olefins (30,33). (The sensitivity of the predictions of the mechanism to the split between Criegee and -H abstraction paths for propylene will be examined sub- sequently.)…”

by hydrolysis-oxidation mechanisms.The particulate sulfates examined in this experiment did not appear to be isotopically coupled with the ambient water vapor in the air masses from which they were sampled. The lack of correlation between the temporal variations of P O of sulfate (Figure 2) and of water vapor (Figure 3) may indicate one or both of the following conditions: (1) the absence of a predominant secondary mechanism of formation in which the A kinetic mechanism for photochemical smog is developed to incorporate recent new information on rate constants and mechanisms. The predictions of the mechanism are compared with smog chamber data on propylene, n-butane, and propyleneln-butane systems. Areas of uncertainty are delineated, and the influence of these uncertainties on the predictions of the mechanism is discussed.

“…The ozonides separated by gas chromatography were characterized by their mass fragmentation [m/z (rel. intensity, %) for secondary but-1-ene ozonide 104 (1, M ϩ ), 75 (10), 58 (9), 57 (12), 47 (8), 46 (6), 45 (10), 42 (11), 41 (7), 31 (23), 30 (17), 29 (100), 38 (35), 27 (37); for secondary hex-1-ene ozonide 104 (1, M Ϫ 28), 90 (4), 75 (7), 73 (6), 71 (5), 60 (17), 58 (16), 57 (23), 55 (9), 45 (14), 44 (59), 43 (25), 42 (15), 41 (57), 39 (22), 31 (12), 30 (11), 29 (100), 28 (26), 27 (42)]. While a very small signal for the molecular ion is observed for secondary but-1-ene ozonide, the highest m/z signal for secondary hex-1-ene ozonide corresponds to a M Ϫ 28 fragment.…”
