The indicated shift of electrons increases the polarity of the reducible bond for the allyl compound XVI and decreases the electron density on the carbon prone to the electron attack4. On the other hand, the shift of electrons for the vinyl compound XVII increases the electron density on carbon, decreases the polarizibility of the C—X bond in a favourable direction, and causes a more difficult reduction than of the saturated analogue. This behaviour parallels the reactivity in some chemical reactions for instance, the solvolysis of the vinyl derivatives XVII is slower than that of the allyl derivative XVI. 

The use of retain samples to routinely examine a statistically sound number of units is a valuable investigative tool. If the retain samples do not reveal any degradation, but other quality markers, such as consumer complaints, manufacturing deviations, and QC profiles, indicate shifts in quality, a problem with the retain sampling method should be considered. On the other hand, if the retain samples... 

Structures of (a) cubo-octahedral Bj2 unit and (b) icosahedral B12 unit. These two units can be interconverted by the displacements of atoms. The arrows indicate shift directions of three pairs of atoms to form additional linkages (and triangular faces) during conversion from (a) to (b), and concurrent shifts of the remaining atoms are omitted for clarity. 

To avoid any misinterpretations concerned with the digit style of numbers, the decimal point is used throughout the book instead of a comma (i.e. computer notation 1.03 instead of 1,03, except for some graphical representations). In representative molecular structures, spin-paired non-bonding electrons around an atom of a molecule are represented (if necessary) by a bold line —in accord with commonly used leivis-structures. Single electrons are represented by a dot A full arrow (-> ) indicates shifts of electron pairs, whereas single electron shifts are... 

The pseudomorphs after fabric were located in an area roughly between H and U on the x axis, and between 3.6 and 9.0 on the y axis. This area corresponds to approximately 52% of the spearpoint s length and 81% of its width. Examination of the spearpoint during the survey phase had already indicated shifts in the geometry of the fabric with respect to the weapon s form (6). 

The IR spectra of (75), where M = Pd or Pt, include vC=N at 1435 cm-1, i.e. there has been a significant increase compared to the free ligand, showing changes in delocalisation patterns.442 IR bands for (76) indicate shifts in ligand modes showing 5-coordination of the thioamide groups.443... 

ScHOOEL has already pointed out the influence of heat on the color of an indicator. He found that boiling a solution of an alkali sensitive indicator shifted the color to the basic side, while the color of acid sensitive indicators was displaced towards the acid side. He explained this on the basis of an increase in the dissociation constant of water. This interpretation is illustrated by the following discussion. 

IV). In the writers opinion, this (and some other indicated shift values) casts doubt on the proposed structure 30. 

The arrows indicate shifting of pairs of electrons as heat is applied.)... 

Figure 16.2.2 summarizes the perceived primary activity and each milestone compound on the way to reaching pencycuron. The compound was found in an indication shift Normally chemists synthesize new compounds intended for a particular activity. With pesticides inquiry, however, a new finding was often seen in a different area from the anticipated one. For instance, the development of pencycuron originated from what was primarily a herbicide project.

The Welsh miner is able to accommodate all of these perspectives in a single narrative. He describes how the union feels at both the national and local level and how miners at his mine decided to support management s decision to install roof bolts. In the following passage, the miner explores the full range of social and institutional perspectives that define his own ambivalence toward this potentially risky technology. Italics in the following excerpt indicate shifts in perspective ... 

Figure 25. NMR spectrum (72.9 MHz) of a perfused rabbit heart. Each trace represents the Fourier-transformed average of 150 transients requiring 5 min total accumulation time. Chemical shifts are expressed in ppm relative to a solution of 0.2 m H3PO4 in 15% HCIO4 contained in a 1-mm diameter capillary tube. Positive values indicate shifts to a higher field than the reference. (A) Fully perfused heart. (B) Same heart and same condition as in (A) but spectrum obtained immediately after ligation of the left anterior descending coronary artery. The bar line calibrates the location of the control phosphate peak. From Hollis et al (1977).

Guo] determined flie boron solubility in metal matrix of alloys contained about 12 mass% Cr, 1.4 mass% B, some other elements and Fe to balance as 0.185 to 0.515 mass% in as-cast martensite and 0.015 to 0.059 mass% after the 750°C tempering. According to [2001Cal] the indicated shifts in the phonon frequencies and identification of additional vibration modes of the melted Fe-8Cr-0.095B (mass%) alloy are the evidences for the interstitial nature of boron soluble in flie alloy.
