Velocity, ionic calculation

Equation 10 is used to calculate the dry deposition velocity for NO2. It is assumed that all of the N02 in the dew came from the dissolution of NO2. A value of 0.03 cm/s is found for the deposition velocity. To calculate the dry deposition velocity for HNO3, it is assumed that the source of dew N03 was the dry deposition of HNO3. The calculated value, 2.0 cm/s, appears high relative to the velocities of other soluble gases such as HCHO (see Tables II and IV) and likely reflects that HNO3 can be adsorbed onto a dry surface. Evidence to substantiate this point appears in the next section. It is also possible that some of the NO3 and/or NO2 arose from the deposition of small amounts of PAN however, the ionic fate of dissolved PAN is not known and therefore more information is required for an assessment of its role in atmospheric corrosion. 

This relationship makes it possible to calculate the maximum ionic conductivity of solid electrolytes. Assuming that the mobile ions are moving with thermal velocity v without resting and oscillating at any lattice site, this results in a jump frequency... 

According to P. Pascal,0 fluorine is diamagnetic the specific magnetic susceptibility is —3447 X10 j and the atomic susceptibilitv calculated from the additive law of mixtures for organic compounds is —63X10-1. Ionic fluorine is univalent and negative. The decomposition voltage required to separate this element from its compounds is 1 75 volts.7 The ionic velocity (transport number) 8 of fluorine ions at 18° is 46 6, and 52-5 at 25° with a temp, coeff. of 0 0238. 

Titrimetric analyses have established that Ki = I05-41 ooa M l and K2 = 10Z-34 0°3 M-1 (54, 58). With use of these values and of conservation equations for both Mg and PP, the respective concentrations of Mgz+, PP], MgPPf, and MgzPP- in any given assay mixture can be readily calculated. Enzymic hydrolysis (PPi 2 P,) was measured in each of a large number of solutions in which the concentrations of the various PPi species varied widely. The enzyme velocities so obtained were correlated with these concentrations and analyzed for mathematical fit to a number of possible kinetic models. [At lower pH additional ionic species are present, for example, HPP-- and MgHPP-". However, at pH 9.1 where enzymic activity is maximal (Section III,A), these protonated species are virtually nonexistent and can be neglected.]... 

The ionic susceptibility/conductivity is a function of the trajectories of the charges at equilibrium that is, y (m (o>) is proportional to the ACF spectrum of the E-projection of the steady-state velocity. One may regard Eq. (394) as a convenient (for numerical calculations) form of the Kubo formula [69] for the diagonal component of the conductivity tensor... 

From the standpoint of the electronic structure, Gadzuk et al. [62] show that the vibrational excitation of desorbed molecules is closely related to the lifetime of the negative ionic state. Hasselbrink [63] discusses that the translational energy obtained from the velocity distribution increases with increasing rotational energy of the desorbed molecules. Both calculations assume a form of the potential energy surface (PES) in the excited state and the assumed form plays an important role. 

The electrophoretic component Vg of the drift velocity of an ion is equal to the electrophoretic velocity of its ionic cloud because the central ion shares in the motion of its cloud. If one ignores the asymmetry of the ionic cloud, a simple calculation of the electrophoretic velocity Vg can be made. 

To know how asymmetric the ionic cloud has become owing to the relaxation effect, one must calculate the distance d through which the central ion has moved in the relaxation time t. This is easily done by multiplying the relaxation time by the velocity v° which the central ion acquires from the externally applied electric force, i.e.,...
