IV compares a few chromatographic data relating to the separation of bromophos-ethyl and dimethoate on the HPTLC pre-coated plate silica gel 60 and the HPTLC pre-coated plate RP-18.

IV compares bond lengths for 8—8 bonds in compounds with 84 structural units —ligand.

IV compares for a series of dienes the yields of 1,2 addition products obtained with Rh as the catalyst precursor under intercalated and homogeneous reaction conditions. The yields of terminal olefins are consistently higher for the intercalated catalyst. The deviation from solution yields are larger when the intercalated catalyst is solvated with methanol than with acetone.0 Methanol swells the interlayers to an average thickness of 12 A, whereas acetone swells the interlayers to w 15 A. Since the more constricted methanol solvated interlayers provide the higher yields of terminal olefins, spacial factors as well as polarization effects induced by the charged silicate sheets may be contributing to the deviations from solution behavior. In this reaction system polarization effects may well be more important than spacial factors in directing hydrogenation transfer because the spacial requirements of the transition states derived from or r 3 allyl intermediates should be very similar.

IV compares oxidant dosage of the two studies. Expected trends between oxidant maximum and oxidant dosage are not seen. Both

IV compares results of short term monitoring obtained from the 3M OVM, and by both instrumental means. This test demonstrates the short term sampling capability of the monitor.

IV compares some of the characteristics of the ozonation reaction with those of some other hydrocarbon reactions whose mechanisms have been studied extensively. The ozonation reaction resembles free radical reactions, such as the abstraction of hydrogen atoms by O—C, in its selectivity

IV compares the concentrations of analyzed inorganics in the feedstock and treated soil. Zinc and lead were the major elements in the feedstock at 70 and 15 ppm, respectively. Both elements showed significantly reduced concentrations in the treated soil.

IV compares the costs and time involved in the RD D permitting process in two different EPA regions.

IV compares the performance of several y spectrometry systems for many nuclides found in the environment. The f -y coincidence system is seen to offer significantly lower detection limits for many of the nuclides. Longer counting times could be used to establish even lower limits of detection, especially for low background systems.

IV compares the present reported limit of detectability of iron, copper, zinc, lead, and cadmium in aqueous solutions with that obtainable with the proposed solvent extraction procedure. Detectability is defined as that concentration of metal which gives a signal twice the variability of the background. Since the amount of metal recovered as shown in Table II was not 100 for most metals, the limit of detectability by this method should be increased by about 5-10 .

IV compares the reactivity ratios of a soft . The lowest ratios are for the 3-fluoro derivative, whereas the differences between the chloro and bromo compounds are not so large. This behavior is similar to that in SNAr reactions. This behavior can be rationalized by symbiotic effects, which favor the soft-soft PhS--Br interaction and the hard-hard MeO-F interaction. A reactivity-selectivity relationship for vinyl bromides of different electrophilicities does not exist.
