Acid-C t lyzed Chemistry. Acid-catalyzed reactions form the basis for essentially all chemically amplified resist systems for microlithography appHcations (61). These reactions can be generally classified as either cross-linking (photopolymerization) or deprotection reactions. The latter are used to unmask acidic functionality such as phenohc or pendent carboxyhc acid groups, and thus lend themselves to positive tone resist apphcations. Acid-catalyzed polymer cross-linking and photopolymerization reactions, on the other hand, find appHcation in negative tone resist systems. Representative examples of each type of chemistry are Hsted below. 

Extended linear chain inorganic compounds have special chemical and physical properties [60,61], This has led to new developments in fields such as supramolecular chemistry, acid-base chemistry, luminescent materials, and various optoelectronic applications. Among recent examples are the developments of a vapochromic light emitting diode from linear chain Pt(II)/Pd(II) complexes [62], a luminescent switch consisting of an Au(I) dithiocarbamate complex that possesses a luminescent linear... 

When solutions of an acid and an alkali are mixed in the correct proportions the resulting solution has no acidic or alkaline character, and on evaporation it gives a solid salt. This reaction is called neutralization because the product has neither acidic nor alkaline properties (Latin, neuter, neither). Neutralization is an example of the quantitative aspects of chemistry acid and alkali react to form a salt in fixed ratios which are not the same for different acids and bases.

As in general chemistry, acid-base reactions are of fundamental importance in organic chemistry. Organic acids and bases, as well as inorganic acids and bases, occur frequently in reactions, and large numbers of reactions are catalyzed by Brpnsted acids and bases and Lewis acids and bases. 

Many aspects of the redox chemistry, acid-base chemistry, and metal complexation chemistry of DOM are manifestations of the H/C and O/C ratios of the DOM. When a complete elemental composition is available, it is even possible to estimate quite well the relative proportions of aliphatic carbon, aromatic carbon, and other forms of carbon in DOM (Perdue, 1984, 1998 Wilson et al., 1987). From a biological and ecological perspective, the structural and compositional information that can be derived from a complete elemental analysis have been shown to relate directly to the bioavailability of DOM to bacterial assemblages in river water (Sun et al., 1997 Vallino et al., 1996 Hunt et al., 2000). 

Turning from physical to chemical properties, let us review briefly one familiar topic that is fundamental to the understanding of organic chemistry acidity and basicity. 

Water natural waters - oxygen and redox chemistry, acid/lDase chemistry and carbonate system drinking water - purification, disinfection, impact of chlorine groundwater - contaminants and remediation wastewater - phosphate, oxygen demand, fate of organic compounds, wastewater treatment (four lectures)... 

Acid-Base Chemistry Acid-base reactions represent another important area of chemistry with applications in engineering, and again we have integrated our coverage into appropriate areas of the text. Initially, we define acids and bases in conjunction with the introduction to solutions in Chapter 3. Simple solution stoichiometry is presented in Chapter 4. Finally, a more detailed treatment of acid-base chemistry is presented in the context of equilibria in Chapter 12. 

With this understanding, we now turn to acid-base chemistry. Acid-base equilibria are determined by a combination of large intramolecular bond energies, characteristic of the gas phase solutes, and large solvation free energies, leading to a delicate balance. To understand this in more detail, we have carried out studies [40,49, 50] related to the reactions... 

In addition to difficulties related to alkylation chemistry, acid may be physically carried out of the reactor due to poor level or pressure control. Troubleshooting requires the engineer to differentiate between physical-and chemical-initiated carry-overs. 

Basic Physical Chemistry for the Atmospheric Sciences covers the fundamental concepts of chemical equilibria, chemical thermodynamics, chemical kineHcs, solution chemistry, acid and base chemistry, oxidation-reduction reactions, and photochemistry. Over 160 exercises are contained within the text, including 50 numerical exercises solved in the text and 112 exercises for the reader to work on with hints and solutions provided in an appendix.
