Full stops

Fullerenes can be considered as a molecular full stop to organic synthesis highly complex and possibly very useful molecules are formed by self-organization of carbon atoms in the vapor phase. Sometimes synthetic chemists are not needed. 

Symbols separated by commas represent equivalent recommendations. Symbols for physical and chemical quantities should be printed in italic type. Subscripts and superscripts which are themselves symbols for physical quantities should be italicized all others should be in Roman type. Vectors and matrices should be printed in boldface italic type, e.g., B, b. Symbols for units should be printed in Roman type and should remain unaltered in the plural, and should not be followed by a full stop except at the end of a sentence.

Titles of periodicals are defined as in the Chemical Abstracts Service Source Index (CASSI), except that full stops have been omitted after each abbreviated word. Abbreviations of words in the texts of Chapters 4, 5 and 6 are those in common use and are self evident, e.g. distn, filtd, cone and vac are used for distillation, filtered, concentrated and vacuum.

If they talked past midnight and Carothers was in a high and happy mood, he drove Labovsky home. Concentrating on their conversation instead of his driving, Carothers almost got a traffic ticket once. A policeman stopped him at a stop sign to say that he had not made a full stop, but Carothers talked his way out of the ticket. 

Later reconstructing the history of this period, Coulson claimed that the development of wave mechanics from Schrodinger to Dirac came to a "full stop" about 1929 insofar as chemistry was concerned. It was one thing to deal with the simplest cases of the H2+ ion and the H2 molecule. These problems hardly were comparable to methane or benzene. "Despondency set in."46 Joseph Hirschfelder later recalled that there were many new techniques to be learned in the 1920s, but then the realization set in that although "nature might be simple and elegant, molecular problems were definitely more complicated.. .. At this point, the theoretical physicists left the chemist to wallow around with their messy molecules while they resumed their search for new fundamental laws of nature."47... 

After 6-12 months, or sooner if the bin is almost full, stop adding any more. 

Forman wrote in a distinctive, often archaic fashion. Where necessary for clarity, punctuation has been added. Existing punctuation has been modernized, usually converting full stops into commas and slashes into full stops. The erratic use of capital letters has been retained when conveying emphasis. Red ink and different scripts are recorded in footnotes where relevant. The word wordle for world is a hallmark of his writings, and the letters have not been un-transposed. Forman s malapropisms remain. 

When the latter is half full, stop the process and withdraw the small glass tube from it, taking care not to wet the constriction. Bring the tube, still in the freezing bath, to the blast lamp and seal it at the constriction. This will take some skill, and it is well to try the manipulation on an empty tube or one half nhe... 

Note that the items are separated by commas, and that the statement ends with a full stop. The parenthesized combination of TLC system code and retention value is called a structure. Seen from outside the parentheses it is just one single object.

The chemical symbols of elements are (in most cases) derived from their Latin names and consist of one or two letters which should always be printed in roman (upright) type. Only for elements of atomic number greater than 103, the systematic symbols consist of three letters (see footnote U to table 6.2). A complete list is given in table 6.2, p.94. The symbol is not followed by a full stop except at the end of a sentence. 

The following one-, two- or three-letter symbols are used to represent the states of aggregation of chemical species [l.j]. The letters are appended to the formula symbol in parentheses, and should be printed in roman (upright) type without a full stop (period). 

These symbols should be printed in roman (upright) type, without a full stop (period). 

Symbols for units should be printed in roman (upright) type. They should remain unaltered in the plural, and should not be followed by a full stop except at the end of a sentence. 

In deriving the regression coefficients byw. and bya.w, we have kept the variable in the subscript after the full stop constant. For this reason these are known as partial regression coefficients. The simple regression coefficients would have been given by... 

Express each measurement as a number separated from its units by a space. If a prefix is required, no space is left between the prefix and the unit it refers to. Symbols for units are only written in their singular form and do not require full stops to show that they are abbreviated or that they are being multiplied together. 

If necessary, show the number of electrons (pairs or individual electrons) clearly. Remember, a. (full stop) may be mistaken for a mark in the... 

Contractions are differentiated from abbreviations by omission of full stop. Thus if Engineering is contracted to Engng, no period follows the abbreviation, whereas if Engineering is shortened to Eng., a period is used. 

The first part of the descriptor indicates the number of atoms in the main chain. The arabic numerals after the full stop indicate the lengths of the branches cited in priority order. A superscript locant for each branch denotes the atom in the part of the molecule already numbered to which the branch is attached. 

Although we have said that translation of the codons could continue to the end of the m-RNA this does not usually happen. Instead translation is terminated by codons that do not bind to amino acyl t-RNA that is, they do not correspond to a particular amino acid, the full-stop codons referred to above. Release of the polypeptide is probably also mediated by a peptidyl transferase, but one which uses water rather than another amino acid as the peptidyl acceptor. GTP and yet another protein factor are also required for release, After chain release m-RNA and t-RNA remain bound to the ribosomes, but we know that the ribosomes can be used several times, so there must be an as yet undiscovered mechanism for releasing the RNA and regenerating free ribosomes. 

Abbreviations should be in capital letters without full stops, and should be kept io the minimum to avoid confusion.
