The isomer shift, S, is the consequence of the Coulomb interaction between the positively charged nucleus and the negatively charged s-electrons. Since the size of the nucleus in the excited state differs from that in the ground state, the Coulomb interaction energies are different as well. The isomer shift is therefore a measure of the s-electron density at the nucleus, and yields useful information on the oxidation state of the iron in the absorber. Isomer shift values are expressed in velocity units, mm/s, and are usually given with respect to the peak position of a reference such as metallic iron. Table 5.2 lists a few isomer shift values of common iron compounds. 

Wfe should note that the units of cm s are similar to the typical velocity units of length per unit time . Since the electron travels from an electrode to a molecule or ion of analyte (or back), it must traverse the distance between them during a certain interval of time. It is legitimate to take ke, as representing a futwHon of the electronic velocity, as charge moves across the electrode solution interface. 

The dotted lines in Fig. 1 show the stopping powers for the different ions at a constant velocity in units of MeV/amu. This unit of energy is very often used in heavy ion radiolysis and it is based on the classical formula for kinetic energy, E = V2 MV, where M is the heavy ion mass. As seen in Eq. (1), the ion velocity is a dominant parameter in energy loss processes and the MeV/amu energy unit is more convenient to use than converting to absolute velocity units. Remember that MeV/amu is actually proportional to the square of the velocity. 

Although individual line positions are given in velocity units, the quadrupole coupling constant is normally quoted in MHz. This facilitates comparison with NQR data. Moreover, data for 129I are usually converted into the value corresponding to 127I, again to assist comparisons. The conversion constants used are ... 

The plot of 1/V vs. 1/[A] for the hydrolysis reaction in the presence and absence of maltose is presented in Figure 5.25. From the x- and y-intercepts for the uninhibited hydrolysis, Km = 3.70 mg/mL and Vm = 135.1 relative velocity units. The plot demonstrates that maltose is a noncompetitive inhibitor because of the same x-intercept. The value of K, can be calculated from the slope ... 

Pad Velocity Units of rotations per minute (rpm) or (cm/sec). If the wafer is rotated off the axis of the pad (as shown in Figure 2.6a), which is common, the pad velocity is also the average relative velocity of the pad with respect to the wafer. Mechanical abrasion rate is also proportional to velocity. Velocity also affects slurry transport across the wafer and the...

Hyperfine interactions such as the chemical isomer shift and quadru-pole splitting are usually referred to in units of mm s , i.e. in velocity units, but the absolute energy of the interaction must be obtained from e = (v/c)Ey as detailed in Section 1.6. 

For the purposes of our discussion we shall look in turn at the uses of each term in Eqn. 6. The Cq term should be noted to be a velocity (units are concentration or amount/time) and not a rate coefficient. The terms and K (whose components can sometimes be dissected by means of fast reaction techniques, vide infra) are used to describe the sensitivity of the enzyme reaction to a variety of changes, as described above. Their ratio k yK, with dimensions of a second-order rate coefficient (M sec ) is also useful and has been called the specificity constant by Brot and Bender [4]. For a single, covalent intermediate pathway (e.g. Eqn. 7, e.g. an acyl-enzyme pathway, this composite constant is insensitive to problems such as non-productive substrate binding, whilst its components are complicated by such problems.

Many of the transport properties of fine particles are comparable to those of gas ph2ise species. They migrate by convective diffusion and can remain in the air of a room for hours and even days, depending on the air exchange rate of the room. In the absence of thermophoretic forces or electric fields, they deposit with roughly equal propensity on all surface configurations and are more able to penetrate narrow spaces than coarse particles. The ratio of the surface accumulation rate (units of mass per unit area per unit time) to the airborne concentration (units of mass per unit volume) is a useful physical parameter that is commonly referred to as the deposition velocity (units of distance divided by time). The deposition velocity is the transfer...
