For a more detailed and critical discussion of the second viral coefficient, the reader is referred to Section IV A. 

For the addition to C6o of two o-quinodimethane groups linked by tethers including methyl deoxycholate, hyodeoxycholate, and chenodeoxycholate units, we refer to Section IV.A.l.c.151... 

Refer to Section IV.E. 1 -2 for methods of analysis and purification of oli-goribonucleotides because they are very similar to those for oligodeoxjri-bonucleotides. RNase-free MilliQ water and sterile containers should be used at all times when processing oligoribonucleotides. 

One of the reasons that ether carboxylates are used in cosmetic products and some household detergents is their good dermatological behavior, as can be seen from several references in Sections IV.A and IV.B. Also their nontoxic and positive ecological properties have contributed to their increased use in these applications. 

The osmium-carbyne carbon bond lengths for the three complexes do not differ significantly, and reference to Table IV indicates that these distances are distinctly shorter than the characterized metal-carbon double bonds of osmium carbene and carbonyl complexes. In both osmium alkylidene and carbyne complexes, then, the metal-carbon multiple bond lengths are largely insensitive to changes in the metal electron density (cf. Section IV,B). 

Refer to Section 6.3 to describe the phases of a clinical trial. Phase IV trials are necessary to maintain a close watch on the efficacy and adverse events of an approved drug when it is administered to the population at large. For example, even a small percentage of adverse events in Phase III trial for several thousand people may translate into a substantial number when a drug is made available to milhons of people. A case in point is Vioxx and Bextra (see Section 2.9). 

Question 11.9 (Refer to section 11.6.2 in connection with this) Hexamethylphospho-ramide (HMPA), OP(NMe2)3, is a good ct-donor, behaving like a typical monodentate phosphine oxide ligand such as PhsPO. A number of complexes of HMPA with uranium(iv) nitrate have been prepared. Green crystals of U(N03)4(hmpa)2 are made thus ... 

Satisfactory working properties of mixtures belonging to non-plastic systems can be attained with the use of organic plasticizers. Frequent use is made of methyl-cellulose or polyvinyl alcohol solutions, mixtures of various waxes, etc. (refer to Chap. IV, Section 2.2). 

The purpose of this section is to introduce standard test methods, practices and guides for evaluation of the various type of corrosion that occur in aluminum. Refer also to Section IV for additional information. 

The reader is referred to Part IV, Chapter 21 in the Accident and Emergency Management Section for details. 

Energy considerations, space, power requirements, etc., also play a role but superimposed on all of the above is the economics associated with the choice. The reader is referred to Part IV, Chapter 21 for the section concerned with Eeonomies and Finance. 

HCCO [145,151] and HCCS [152], The key points of this approach will be described in Section IV.2. For a more detailed description, the reader is referred to the original references and the reviews [18,153,154]. 

In Section IV.A.4, we show what this general model looks like in the case of H electronic states of symmehic tetraatomic molecules. The situation in H states of asymmetric tetraatomics is briefly discussed in Section IV.B, where we present the handling of a concrete case, the X Uu state of the HCCS radical. For A states the reader is referred to original references [18,149,150,153]. 

Some reference to the use of nitrous acid merits mention here. Primary aromatic amines yield diazonium compounds, which may be coupled with phenols to yield highly-coloured azo dyes (see Section IV,100,(iii)). Secondary aromatic amines afford nitroso compounds, which give Liebermann a nitroso reaction Section IV,100,(v). Tertiary aromatic amines, of the type of dimethylaniline, yield p-nitroso derivatives see Section IV,100,(vii). ... 

Most of the substitution reactions of di-, tetra, and hexa-hydro-carbolines and of their oxo derivatives are similar to those of the parent indole or indolenine derivatives. Nitration and bromination of harma-line (l-methyl-3,4-dihydro-j8-carbolme) are referred to in Section IV, A, 1. Sulfonation and azO COupling ° proceed as expected for indole derivatives. The preparation of chlorinated and iodinated derivatives of 6-nitroharmaline has been reported,but their structures have not been established. 

The interesting work of Hahn and Hansel, who prepared a tetracyclic lactam by intramolecular cyclization of the condensation product of tryptamine and a-ketoglutaric acid, is referred to in Section IV, B, 2. Condensation of tryptamine with a,a -diketopimelic acid (403) led, presumably by way of the 1-substituted tetrahydro-)S-carboline (404), which could not be isolated, to a product to which the tetracyclic structure 405 was assigned. 

Polya s main results on tree enumeration are summarized at the beginning of Section IV of his paper. His equation (4.8) gives the functional equation for the generating function of rooted labelled trees, from which Cayley s result, referred to above, follows... 

References for the molecular geometries used in generating the drawings are given in Section IV. 1. Effort was made to make these as up-to-date as possible. For this reason the geometry references are not always the same as those used to determine the ab initio orbital energies. 

In this section, only those studies, all of relatively recent date, that particularly emphasize the determination of rate-determining process steps and the application of the relatively advanced theoretical models discussed in Section IV will be reviewed. For earlier studies of overall reaction kinetics, the reader is referred to the publications of Hall et al. (HI) and Kolbel (K6). 

Kolbel et al. (K16) examined the conversion of carbon monoxide and hydrogen to methane catalyzed by a nickel-magnesium oxide catalyst suspended in a paraffinic hydrocarbon, as well as the oxidation of carbon monoxide catalyzed by a manganese-cupric oxide catalyst suspended in a silicone oil. The results are interpreted in terms of the theoretical model referred to in Section IV,B, in which gas-liquid mass transfer and chemical reaction are assumed to be rate-determining process steps. Conversion data for technical and pilot-scale reactors are also presented.
