Two final concerns must be addressed surface oxidation state and temperature dependence. Whenever one deposits a redox-active species on a metal surface, the oxidation state of the adsorbate (and therefore the OMTS bands) may change. One example is the adsorption of a biaxially substituted dicyano cobalt phthalocy-anine salt, MCoPc(CN)2 (where M = K or Cs), on gold to form the reduced species CoPc [111]. A second example is provided by the adsorption of TCNE on gold, silver, and copper. In that order, the charge state of TCNE on the surface ranges from 0 to 3, and the OMTS reflects these changes.

Silver nitrate is very soluble in water-free pyridine. The solid isolated from pyridine was temperature dependent wih maximum solvation occurring at low temperatures. Thus below -25 °C, Ag(py)2N03-4py was reported to be the stable solid.74 From aqueous pyridine, the bis... 

Flo. 9. Temperature dependence of conductivity of semiconductor pellets with and without added 10% wt of silver powder. The logarithm of structure-independent conductivity is plotted as a function of the reciprocal absolute temperature (degrees Celsius on top of the figure). Full lines are measured, dotted parts extrapolated (79). (Copyright by the Universite de Liege. Reprinted with permission.)... 

The determination of n from measurement of peff is the most familiar application of magnetic susceptibility measurements to inorganic chemists. To the extent that the spin-only formula is valid, it is possible to obtain the oxidation state of the central atom in a complex. Thus an iron complex with a peff of 5.9B.M. certainly contains Fe(III) (high-spin d5) and not Fe(II). The diamagnetism of AgO rules out its formulation as silver(II) oxide, because Ag2+ has an odd number of electrons (d9) and should be paramagnetic it contains Ag(I) and Ag(III), in equal amounts. There are, however, a number of pitfalls, especially if reliance is placed on a single measurement at room temperature. The Curie law is rarely obeyed within the limits of experimental error. This means that the measured peff is somewhat temperature-dependent. A number of factors can be responsible for deviations from ideal Curie (or even Curie-Weiss) behaviour, and/or from the spin-only formula. 

Problems with nonspecific background silver deposition background silver deposition may result from the use of poor-quality antibodies, incorrectly diluted antibodies, old silver-enhancing solutions, poor-quality distilled water, or incorrect silver enhancement times. The silver enhancement procedure is temperature dependent and where laboratory temperatures vary a lot, especially at different times of the year, it is useful to construct a standardized temperature-enhancement time graph and keep it readily available at the bench (Fig. 3). As an example, adequate silver enhancement may take only 5 min at 25°C whereas the same result may take up to 15 min to obtain at 15°C. Enhancement times may be controlled more precisely by storing the enhancer components in the refrigerator at...
