I A sketch of the mass spectrum of elemental carbon is shown. The large peak is due to C, and the smaller peak to the left is C. The size of the peak here is somewhat exaggerated it would actually be just 1 99 the size of the peak.

I A tin can is usually tin-plated steel. If the tin coating is scratched to expose the underlying steel, iron in the steel will corrode rapidly.

I A typicai iN2 curve of an infilled RC frame building. Y and NC indicate yield and near collapse points.

I A typical preparation scheme of PPV precursor polymers, from bis-sulfonium salt, soluble polyelectrolyte precursor. to heat-converted PPV.

I A typical three-layer light-emitting device.

I absolute accelerations yi, yj and y6 considered in the identification procedure.

I Absorption and phos-

I According to the Arrhenius equation, a plot of In it vs. 1 T should give a straight line, with a slope equal to -EJR. Such a plot is frequently used to determine the activation energy of a reaction.

I Acid-catalyzed deesterification of DMBZMA copolymers.

I Acrolein s mesomeric stmctures. The atoms are numbered from the left to the right

I Activity coefficients of benzene and cyclohexane in their mixture at 77.6 C computed from azeotropic data u.sing the van Laar model.

I ADC bit dull grading codes—bold characters for fixed-cutter bits .

I Addition polymerization often proceeds by a free radical mechanism, featuring initiation, propagation, and termination steps. Conditions are chosen so that the initiation and termination steps occur infrequently. Each propagation step adds one monomer unit to the growing polymer chain.

I AFtermaih of the explosion.

I Ahsorpiion scan of a chromatogram containing 200 ng dehydroascorbic acid per chromatogram zone.

I Aldol reaction of benzaldehyde with silyl enol ether I in water-THF

I Alfred Nobel s invention of dynamite provided a powerful explosive in solid form. The actual explosive in dynamite is nitroglycerin, whose molecular structure is shown. Nitroglycerin is a liquid under ordinary conditions, so its use as a commercial explosive was extremely hazardous.

I Alkylation of butanone.

I All three Droscra samples show the violet-brown as the main zone at R, 0.45.

I also acknowledge the Cambridge Crystallographic Data Centre for kindly supplying many crystallographic data used in this book.

I also plotted in the same plane part of the pp 0.2 ensemble, and a part of the pp 0.9 ensemble in the picture to give an indication of the basin of attraction and commitment to the stable states.

I also shows the hydrogen sulfide pressure profile in the case of countercurrent operation. It can be seen that the main part of the bed where high catalyst activity is needed now operates under H2S-lean conditions. Only a relatively small part of the bed operates under H2S-rich conditions, and in this part suppression of catalytic activity is less serious, since here the conversion of relatively reactive compounds takes place. Therefore, the countercurrent mode of operation will be clearly superior, and this is the more true the deeper the desulfurization target.

I am immediately frustrated when there are difficulties in technical issues

I An asymmetrical enzyme distinguishing between identical substituents on a symmetrical molecule.
