We will recall briefly the different families of hydrocarbons without attempting to give a summary of a course in organic chemistry. The reader is particularly encouraged to refer to general reference works for information concerning the nomenclature and properties of these compounds (Lefebvre, 1978). 

Tabular summaries of the lUPAC rules for alkane and alkyl group nomenclature appear on pages 96-98...

A summary of nomenclature rules for carboxylic acid derivatives is given in Table 21.1.

Taking a value of 107 for N would mean that in our galaxy (with its perhaps 100 billion stars), there could be several million planets with life forms capable of interstellar communication. However, if these were distributed statistically, the nearest would still be 200 light years away from Earth. One point is important the term probability used in the Drake equation is interpreted in the sense of subjective probability (a term from the nomenclature used by statisticians and probability theorists), as the numerical value of this probability is determined only by the experience of the scientist concerned (Casti, 1989). Casti also provides more information on the Drake factors (apart from the factor fs) in the chapter Where are they then In summary, we can say that the Drake equation is a first attempt to quantify the ETI problem in order to move from the area of science fiction and pure speculation to that of serious scientific debate. 

In the/flc isomer, the three chloride ions are located on the corners of one of the triangular faces of the octahedron. In the mer isomer, the three chloride ions are located around an edge (meridian) of the octahedron. The IUPAC system of nomenclature does not use this approach. A summary of the IUPAC procedures is presented in the book by Huheey, Keiter, and Keiter that is cited in the references listed at the end of this chapter. 

This contribution is an attempt to close this gap and therefore the organization of the chapter will be as follows. After a short outline of problems related to the nomenclature and delimitation of genera within the tribe Tabemaemontaneae, a summary of chemically investigated Tabernaemontana plants will be presented. Subsequently, the structure elucidation and chemistry of the most relevant alkaloids will be discussed. Finally, some noteworthly pharmacological activities will be outlined. 

A number of points are relevant for a full crystallochemical characterization for each of them a few noteworthy remarks will be presented in the following. To this end, crystallographic conventions, nomenclature and symbols will be used. For a summary of these and of the corresponding definitions the most important reference book is International Tables for Crystallography (Hahn 2002). 

A report by the International Union of Crystallography Commission on Crystallographic Nomenclature (Lima de Faria et al. 1990) presents a concise description of similar alternative notations, a summary of which is in Table 3.4. 

All electrons in atoms can be described by means of these four quantum numbers and, as first enunciated in 1926 by Pauli in his Exclusion Principle, each electron in an atom must have a unique set of the four quantum numbers. A summary of the electron shells and of the corresponding maximum numbers of orbitals, and electrons, is shown in Table 4.2 where each shell is defined by the value of the principal quantum number (K = 1, L = 2, etc. according to X-ray spectroscopy nomenclature). 

Besides the crystallographic and chemical symbols and nomenclature previously introduced, a few special symbols have been used in this chapter. Generally, for nearly all the metals (Me), a summary is given of their reactivity with the other elements. This is outlined in the text and in figures representing the Periodic Table. In some cases, more than one table is provided for each element. The different binary systems Me-X are identified by the position in the Table of the element X, and their characteristics are briefly described by one of the following symbols inserted in the corresponding box ... 

It is our intention to present strategies based on chemically induced phase separation (CIPS), which allow one to prepare porous thermosets with controlled size and distribution in the low pm-range. According to lUPAC nomenclature, porous materials with pore sizes greater than 50 nm should be termed macroporous [1]. Based on this terminology, porous materials with pore diameters lower than 2 nm are called microporous. The nomination mesoporous is reserved for materials with intermediate pore sizes. In this introductory section, we will classify and explain the different approaches to prepare porous polymers and to check their feasibility to achieve macroporous thermosets. A summary of the technologically most important techniques to prepare polymeric foams can be found in [2,3]. 

In the following sections a short summary of the better known of the incompletely characterized allotropes is given. The data are summarized in Table IV for details, we refer to reviews (25, 65) or the original literature. The study of the latter is, however, often hard, as different authors use different conventions and nomenclature, and many researchers are not familiar with all earlier literature. We use the... 

The first publication of the lUPAC in the area of macromolecular nomenclature was in 1952 by the Sub-commission on Nomenclature of the then lUPAC Commission on Macromolecules, which drew on the talents of such remarkable individuals as J. J. Hermans, M. L. Huggins, O. Kratky, and H. F. Mark. That report [1] was a landmark in that, for the first time, it systematized the naming of macromolecules and certain symbols and terms commonly used in polymer science. It introduced the use of parentheses in source-based polymer names when the monomer from which the polymer is derived consists of more than one word, a practice that is now widely followed, and it recommended an entirely new way of naming polymers based on their structure that included the suffix amer , a recommendation that has been almost totally ignored. After ten years, the Sub-commission issued its second report [2], which dealt with the then-burgeoning field of stereoregular polymers. A revision [3] of definitions in the original report appeared four years later. In 1968, a summary report [4] of the activities of the Subcommission was published. 

The amount of the loan is called the principal P. The longer the time for which the money is loaned, the greater the total amount of interest paid. The future amount of the money F is greater than the principal or present worth P. The relationship between F and P depends upon the type of interest used. Table 9-20 is a summary of the nomenclature used in time value of money calculations. 

The nomenclature of phosphorus commpounds is formidable. Even for a specialist it offers many difficulties, especially as many compounds are named in more than one way. Some important changes have therefore taken place recently. Some of the names of the different classes will be found in (B-79MI11700) and (B-74MI11700). A short summary of the names of the most important monocyclic ring systems seems necessary at this point (Table 1). 

The scarcity of reviews1 and recent interest in thiochromanones and related compounds calls for a comprehensive summary of this area of heterocyclic chemistry. The apparent similarity between these systems and the naturally occurring chromanones, chromones (flavones), chromenes, etc., is responsible for the continued importance of these sulfur heterocycles. Chemical Abstracts (through November, 1973) has been employed as the principal reference source and nomenclature guide for this review.
