Parentheses with

In the condensed form, the configurational symbol and the letter denoting ring size are omitted. It is understood that the configuration is D (with the exception of fucose and iduronic acid which are usually L) and that the rings are in pyranose form unless otherwise specified. The anomeric descriptor is written in the parentheses with the locants. 

Explain the meaning in organic formulas of a pair of parentheses with no subscript behind it, such as in CHjCHjCHfCH.K H . 

After the ligands are named, the name of the metal is given next, with its oxidation state indicated by Roman numerals in parentheses with no spaces between the name of the metal and the parentheses. 

STEP SIX Substitute appropriate rate constants for the arrows (from step four) and the numbers in parentheses with the expressions obtained from step three. Thus,... 

Comparison of the last term in the parentheses with the diagram of Figure 6.1-3 shows that it is equal to the slope of the chord connecting the points (x, y ) and (xy yj. If the equilibrium curve is a straight line, then it is the slope m. Thus ... 

Menthyl = (1/ ,2S,5/ )-2-isopropyl-5-methylcyclohexyl. Configuration of carbon atoms 1 and 2 for major isomer in parentheses. With ethyl diazoacetate the same trans.cis product ratio was obtained, and % ee s were 91(cis) and 1 l(trans). 

Table 6. Fluorescence peaks and intensities in parentheses with excitation X at 280nm of a-amylase containing tyrosine and tryptophan dissolved in 90% ethanol 30, distilled water, Merc cor 30 in 90% ethanol and Merc cor 30 in distilled water. Sodium acetate buffer (pH 4.7) was also used.

Repeated groups can be condensed to a single repeat inside parentheses, with the number of repeats listed as a subscript. Caution should be exercised that subscripts, superscripts and in-line numbers are clearly distinguished from one another. 

The free electrons and holes are denoted as e and h, respectively. The simplest defect clusters are usually written by listing all point defects between parentheses, with subsequent superscript showing the cluster effective charge. Note that parentheses and brackets are sometimes used also to indicate local coordination in the lattice. 

Figure 24. Photolytic charge separation with nanocrystalline zeolite (a) correlation of percentage crystallinity of nanocrystals (shown in parentheses) with PVS" production (b) comparison of the rate of PVS " radical generation for nanocrystalline zeolite X and micronsized zeolite Y.

We may readily show this by differentiation of the term in parentheses with respect to a and setting it equal to zero. 

The names of monatomic cations always start with the name of the metal, sometimes followed by a Roman numeral to indicate the charge of the ion. For example, Cu is copper(l), and Cu is copper(ll). The Roman numeral in each name represents the charge on the ion and allows us to distinguish between more than one possible charge. Notice that there is no space between the end of the name of the metal and the parentheses with the Roman numeral. 

There are many polyatomic anions that can take the place of monatomic anions. For example, zinc hydroxide, used as an absorbent in surgical dressings, has a similar structure to zinc chloride, which is used in embalming and taxidermist s fluids. The hydroxide ion, OH , plays the same role in the structure ofZn(OFl)2 as the chloride ion, Cl , plays in ZnCl2. (Note that to show that there are two hydroxide ions for each zinc ion, the OF is in parentheses, with a subscript of 2.)... 

This expression is identical to the desired result if we identify the term in the parentheses with c / Me. 

In contrast, the a-protons in pyrroles and indoles have positive shifts (0 05-0 30 p.p.m.), and the )3-protons have negative shifts ( 0-50 p.p.m.). AT-Alkyl protons have large positive shifts, decreasing in magnitude with increase in length of the alkyl chain. Some typical A values for some nitrogen heterocycles are shown in parentheses with the appropriate molecular formulae (43—46). 

The 1 1 complex shown in (69) has been proposed by Danyluk to account for the pyridine-induced shifts (AcsHjN P p m ) observed for benzyl acetone (70). These shifts are given in parentheses with its... 

The carbonyl plane rule is also applicable to pyridine-induced solvent shifts in some ketones. However, the reference plane is displaced so that it passes through the a-carbons rather than the carbonyl carbon (see 76). The shifts of a-tetralone (77) shown in parentheses with its molecular formula serve as an example to illustrate the modified rule. 

The strongest peaks in the mass spectra of 375 important organic solvents and other liquid reagents are listed in this table. The ehn value for each peak is followed by the relative intensity in parentheses, with the strongest peak assigned an intensity of 100. The peaks for each compound are listed in order of decreasing intensity. Compounds are listed by the name used in this Handbook, with other common names given in parentheses. 

Bound neutron scattering lengths and neutron cross sections averaged over a Maxwellian spectrum at 30 keV for astrophysical applications are also presented. A list of the major references used is given below. The literature cutoff date is January 2003. Uncertainties are given in parentheses. Parentheses with two or more numbers indicate values to the excited state(s) and to the ground state of the product nucleus.
