Greek letters, listed

The lines emitted by excitation of a shell X form the X series. In a given series, the lines are identified by Greek letters listed by decreasing order of intensity (Fig. 4.2). 

All measuring units are indicated by roman symbols. Except for greek letters, physical and physico-chemical properties are, although in the figures represented by roman symbols, in the text and the equations consistently indicated by italic symbols in accordance with the following list. 

Dimensional and mathematical symbols used in this Code are listed in Mandatory Appendix IV, with definitions. Uppercase and lowercase English letters are listed alphabetically, followed by Greek letters. 

Greek letters are often used in science and engineering. Table 21.2 lists some of the common uses. 

Commercial fats solidify in several crystalline polymorphic forms. Two desirable stable forms are commonly designated by the Greek letters beta ((3) and beta-prime (p )- Table 2 (7) lists many common fats and oils and their most commonly exhibited polymorphic crystalline form. 

Tables III-XVII give calculated permanent moments. Selected comparisons with experimental values or calculations of others are also listed. All values are in atomic units, and traceless rather than Cartesian forms are distinguished with Greek letters, 6 (quadrupole) and G (octupole). Coordinates for the atomic centers are listed. These specify the geometry used, which were equilibrium geometries, and implicitly the multipole expansion center (x = 0, y = 0, z = 0). The moments are given at both the SCF level and at the well-correlated level of coupled-cluster theory [95-102]. ACCD [103-106] was the particular coupled-cluster approach, and the moments were evaluated by expectation [102] with the cluster expansion truncated at single and double substitutions.

Abbreviations are listed in alphabetical order without regard to case. Entries beginning with Greek letters fall at the end of the table. 

The crystal structures of the aUotropic forms of the elements are presented in terms of the Pearson symbol, the Strukturbericht designation, and the prototype of the structure. The temperatures of the phase transformations are listed in degrees Celsius and the pressures are in GPa. A consistent nomenclature is used, whereby all allotropes are labeled by Greek letters. The lattice parameters of the units cells are given in nanometers (nm) and are considered to be accurate to 2 in the last reported digit. 

When using the list of sjonbols, as is done in the following pages, the use of the same symbol for more than one concept is to be avoided. The Latin alphabet proves to be insufficient for this purpose, so that Greek letters have had to be added, whilst further variations have been made possible by the addition of suffixes [12]. 

Entries are listed in alphabetical order. The main entry title is printed in bold type, followed by synonyms in bold italics. Numbers, Greek letters and configurational numbers/letters at the beginning of the name are ignored when allocating in alphabetical order, e.g. O-Acyl isopeptide method is listed under A, aj -macroglobulin is listed under M, while 8-quinolyl ester is listed under Q. 

Those symbols which are only used once in the text do not appear in this listing. Familiar mathematical functions are also not included, nor are quantities that are simply intermediates in a derivation. Capital letters are listed before lowercase letters. Greek letters are listed at the end. 

The C-NMR spectrum of an ethylene-propylene copolymer, containing approximately 97% propylene in primarily isotactic sequences, is shown in Figure 10.3. Major resonances are numbered consecutively from low to high field. Chemical shift data and assignments are listed in Table 10.1. Greek letters are used to distinguish the various methylene carbons and designate the location of the nearest methine carbons. 

An internationally accepted chemical notation makes use of symbols to represent elements and compounds, and advises on naming chemical compounds. In this notation, the elements are represented by one or two letters, many of which are drawn from the elements Latin or Greek names. The number of atoms of an element in a molecule is represented by a subscript written after the symbol thus Au (the first two letters of aurum, the Latin name for gold) represents an atom of gold Cu (the first two letters of cuprum, the Latin name for copper), an atom of copper and C (the first letter of carbon), an atom of carbon O represents an atom of oxygen and 02, a molecule of oxygen. The symbols listed below provide examples of the presently accepted form of chemical notation ...
