Seconds symbol, spacing

Exception 1 Do not leave a space between a number and the percent, angular degree, angular minute, or angular second symbols. 

The second line space group symbol, followed by a, b, c, /3 or y. 

The first line of the Z-matrix consists solely of the label for this atom. An atom label is made up of its atomic symbol optionally followed by an integer (no spaces), used to distinguish it from the other atoms of the same type (e.g. HI for the first hydrogen, H2 for the second one, and so on). 

That the use of symbolic dynamics to study the behavior of complex or chaotic systems in fact heralds a new epoch in physics wris boldly suggested by Joseph Ford in the foreword to this Physics Reports review. Ford writes, Just as in that earlier period [referring to 1922, when The Physical Review had published a review of Hilbert Space Operator Algebra] physicists will shortly be faced with the arduous task of learning some new mathematics... For make no mistake about it, the following review heralds a new epoch. Despite its modest avoidance of sweeping claims, its theorems point like arrows toward the physics of the second half of the twentieth century. ... 

Class 3 is obtained by introducing a twofold axis of rotation, symbolized by below the motif on the line of translation. The important thing to note here is that in addition to the C2 operation explicitly introduced (and all those just like it obtained by unit translation) a second set of C2 operations, with axes halfway between those in the first set is created. In space symmetry (even in ID space) the introduction of one set of (equivalent) symmetry elements commonly creates another set, which are not equivalent to those in the first set. It should also be noted that had we chosen to introduce explicitly the... 

Second, the chemical shift can be recognized by the fact that it is directly proportional to the transmitter frequency, v. If we double v, the chemical shifts double. In contrast, the first-order spin-spin splittings remain the same. By this we mean that the magnitude (in Hz) of the spacing between the lines of a split resonance is independent of the transmitter frequency, v. This spacing corresponds to what is called the spin-spin-coupling constant, or simply the coupling constant, and is symbolized by J. 

Figure 5.6 Schematic drawing of the oven used for the evaporation of magnesium (Mg) and the essential apparatus for angle-resolved electron spectrometry around the oven. The source volume which also provides a centre of reference is marked by the symbol S. The oven itself is shown in the third quadrant for the symbols characterizing the oven see main text. The direct vapour beam is stopped by the baffle B (placed in the first quadrant). The dashed curves starting from S indicate the angular ranges in which the emitted electrons are accepted by the monitor analyser (second quadrant, mon. , fixed in space), and by the two extreme positions of a rotatable sector CMA (fourth quadrant, pos. 1 , pos. 2 , respectively).

The first column (Code) in Table 3 is the two-letter code assigned to that coordination sphere type and the second column (Sub) indicates which MOLPAK subroutine contains the procedure to build coordination spheres of that type. Some procedures employ common steps and more than one procedure may be contained in a particular subroutine. Columns 3 and 4 give the crystal system (CS) and Z value, respectively. The remainder of each row identifies the relationships of the molecules in the coordination sphere to the central molecule and their distribution in an orthogonal coordinate space. The symbols are... 

Spacing, hyphens, and italics. When a unit symbol is given after a number, a space is always left between the number and the symbol with the exception of cases where the symbol appears in the superscript position, such as degree, minute, and second of plane angles. The symbol for degree Celsius may be written either with or without a space before the degree symbol. For example,... 

Figure 5. The distributions of the recrossing trajectories over configurational surface S qi = 0) at time t = 0 on the phase-space planes (pf (p,q), (p,q)) at E = 0.5e, where most modes are strongly chaotic—except 4i(p,q). (a) First and (b) second orders The circle and triangle symbols denote the system trajectories having negative and positive incident momenta p (t = 0) on the S(qi = 0), and the open and filled symbols denote those whose final states were predicted correctly and falsely by Eq. (11), respectively [45].

Take care to separate symbols in compound expressions by a space to avoid the potential for confusion with prefixes. Note, for example, that 200 m s (metre seconds) is different from 200 ms (milliseconds). 

The arrangement of this table has much in common with that of Appendix B. See the description there for the reaction considered, and a list of the symbols used to indicate the experimental method. In the second column, gas, liquid, and solid have their usual meaning. Solutions are indicated by the name of the solvent appearing in the second column. As in Appendix B, in the first three and last three columns only a blank space means the entry above is to be carried down. In the other columns a blank space means the information is not known to us. 

The point group symbol, in which rotation axes and mirror planes can be substituted with allowed screw axes or glide planes, respectively, is added as the second part of the international space group symbol.
