At this point the reader may feel that we have done little in the way of explaining molecular synnnetry. All we have done is to state basic results, nonnally treated in introductory courses on quantum mechanics, connected with the fact that it is possible to find a complete set of simultaneous eigenfiinctions for two or more commuting operators. However, as we shall see in section Al.4.3.2. the fact that the molecular Hamiltonian //coimmites with and F is intimately coimected to the fact that //commutes with (or, equivalently, is invariant to) any rotation of the molecule about a space-fixed axis passing tlirough the centre of mass of the molecule. As stated above, an operation that leaves the Hamiltonian invariant is a symmetry operation of the Hamiltonian. The infinite set of all possible rotations of the... 

By the end of their college career, most chemistry students have noticed that the information being disseminated in their third- and fourth-year chemistry classes-level seems to conflict with what was taught in introductory courses. 

This chapter is in no way meant to impart a thorough understanding of the theoretical principles on which computational techniques are based. There are many texts available on these subjects, a selection of which are listed in the bibliography. This book assumes that the reader is a chemist and has already taken introductory courses outlining these fundamental principles. This chapter presents the notation and terminology that will be used in the rest of the book. It will also serve as a reminder of a few key points of the theory upon which computation chemistry is based. 

Oligonucleotide synthesis involves specialized blocking and coupling reactions the chemistry of which is beyond the scope of a typical introductory course The in terested reader is referred to http //WWW bi umist ac uk/ users/dberrisford/1 MBL/ nucleicacidB html... 

Analytical chemistry is often described as the area of chemistry responsible for characterizing the composition of matter, both qualitatively (what is present) and quantitatively (how much is present). This description is misleading. After all, almost all chemists routinely make qualitative or quantitative measurements. The argument has been made that analytical chemistry is not a separate branch of chemistry, but simply the application of chemical knowledge. In fact, you probably have performed quantitative and qualitative analyses in other chemistry courses. For example, many introductory courses in chemistry include qualitative schemes for identifying inorganic ions and quantitative analyses involving titrations. 

A number of gravimetric methods, such as the determination of Ct in a soluble salt, have been part of the standard repertoire of experiments for introductory courses in analytical chemistry. Listed here are additional experiments that may be used to provide practical examples of gravimetry. 

In this chapter, we analyzed the process of teaching QM from a set of axioms in an attempt to identify why so many students are confused and dissatisfied at the end of the typical introductory course. Although students majoring in Physics or Chemistry eventually do master the subject and become effective practitioners of QM, those students who have an introductory course as...

Solubility is a complex phenomenon that depends on the balance of several properties. A complete understanding of solubility is beyond an introductory course, but the general features of solubility are summarized by the expression like dissolves like. 

Battery technology continues to advance at a steady pace. Lithium batteries and nickel-metal-hydride batteries are now commonplace. These new rechargeable batteries eliminate the need for toxic cadmium and store more energy per unit mass. The detailed chemistry that underlies the newest advances in battery technology involves principles that are beyond the scope of an introductory course. 

The synthesis of transition metal compounds must be tailored to a particular product. The details are complex, and existing patterns of synthesis contain so many exceptions that an overall view is beyond the scope of an introductory course in chemistry. 

Classical process control builds on linear ordinary differential equations and the technique of Laplace transform. This is a topic that we no doubt have come across in an introductory course on differential equations—like two years ago Yes, we easily have forgotten the details. We will try to refresh the material necessary to solve control problems. Other details and steps will be skipped. We can always refer back to our old textbook if we want to answer long forgotten but not urgent questions.

The training of most pathologists in statistics remains limited to a single introductory course which concentrates on some theoretical basics. As a result, the armertarium of statistical techniques of most toxicologists is limited and the tools that are usually present (t-tests, chi-square, analysis of variance, and linear regression) are neither fully developed nor well understood. It is hoped that this chapter will help change this situation.

The form of the equilibrium constant in Equation (10.21) is different from that presented in introductory courses. It has the advantages that 1) it is explicit that Kp is a dimensionless quantity 2) it is explicit that the numerical value of Kp depends on the choice of standard state but not on the units used to describe the standard state pressure the equilibrium constant has the same value whether P° is expressed as 750.062 Torr, 0.98692 atm, 0.1 MPa, or 1 bar. 

The field of polymers is expanding at a rapid rate with too much fundamental material to be handled in a single introductory course, yet the basic elements have been included in this text. Some topics that are today considered to be fundamental were not known a decade ago. Each of the fundamental topics are placed into perspective in the current text building upon the core courses of chemistry—organic, physical, inorganic, and analytical. 

We close by apologizing that you may find the following chapters described by some combinations of superficial, incomplete, random, and wrong. However, we need make no apolo for this in an introductory course if you find the material challenging and fun There are many complete texts and monographs on each of these subjects, and any student wanting to know more about them should locate these books or take relevant courses. 

We regard the essential aspects of chemical reaction engineering to include multiple reactions, energy management, and catalytic processes so we regard the first seven chapters as the core material in a course. Then the final five chapters consider topics such as environmental, polymer, sohds, biological, and combustion reactions and reactors, subjects that may be considered optional in an introductory course. We recommend that an instmctor attempt to complete the first seven chapters within perhaps 3/4 of a term to allow time to select from these topics and chapters. The final chapter on multiphase reactors is of course very important, but our intent is only to introduce some of the ideas that are important in its design. 

Most texts strive to be encyclopedias of a subject from which the instmctor takes a small fi action in a course and that are to serve as a future reference when a student later needs to learn in detail about a specific topic. This is emphatically not the intent of this text. First, it seems impossible to encompass aU of chemical reaction engineering with less than a Kirk-Othmer encyclopedia. Second, the student needs to see the logical flow of the subject in an introductory course and not become bogged down in details. Therefore, we attempt to write a text that is short enough that a student can read aU of it and an instmctor can cover most of it in one course. This demands that the text and the problems focus carefully. The obvious pitfall is that short can become superficial, and the readers and users will decide that difference.
