Absorption in others

When the adsorption process does not significantly change the molecular molar absorptivity (in other words, i = b)> then ... 

Thus in a uniform positive column discharge, the simultaneous occurrence of these two excitation processes by electron impact to an extent that would leave a considerable margin for energy absorption in other processes provides a mechanism that could account for the highest observed values given in Tables IV and V. But the crucial question is whether this mechanism can account for the trend of P/p and rj with X/p and with the current density j, and can also account for the absolute magnitudes observed. 

Marzulli and Maibach 1984 Bronaugh et al. 1986). The literature on the effect of age and sex on percutaneous absorption in other species, where more data are available, is confused. For example, it was reported (Banks et al. 1990) that the dermal absorption of certain marker compounds was lower in older rats but that, for different compounds, the reverse was the case (Hall et al. 1992) or indeed that age did not influence dermal absorption in rats (Dick and Scott 1992). Skin permeation in the hairless mouse generally increases with age, corresponding to the single hair cycle, but decreases with a return to the hairless state (Behl et al. 1984a,b). 

The term neutronic purity as used herein has no necessary relation to chemical purity and merely refers to the absence of foreign material having the characteristic of relatively great neutron absorption. In other words, a substance may be said to have high neutronic purity, if the total amount of other material therein is incapable of absorbing a substantial number of neutrons and is thus ineffective to poison the nuclear fission chain reaction. 

The fluctuation-dissipation theorem relates the correlations to absorption in other words, the scattering function is proportional to the imaginary part of a generalised (Q and to dependent) susceptibility, In the zero-frequency, zero-wavevector... 

Zta case occurs when the glass is infinitely thin and has no absorption. In other words, it is a measure of reflection losses from the air to glass surfaces. It is dependent on, and calculated from, the glass s index of refraction at each wavelength. 

The photochemical reaction of a material starts with photon absorption. In other words, only the photons absorbed by the molecule can bring about photochemical reactions. This is the first law of photochemistry, also called the Grotthuss-Draper law. The second law of photochemistry is one molecule is activated when one photon is absorbed. This is called the Stark-Einstein photochemical equivalence law. Generally, a particular group in an irradiated molecule absorbs a photon with an appropriate wavelength. When photoabsorption occurs, the molecule in the ground state is... 

Conjugation with aromatic rings, as in the stilbenes [39,97], does not influence the position of the 965 cm" band, but it is displaced to sUghtly lower frequency when conjugated with acetylenic links [87]. The intensity of this absorption in other substituted stilbenes has been studied by Orr[119], who finds significant alterations in band width where steric effects are likely. 

It should be noted that, when using a poorly-prepared sample, scattering of the incident radiation may result in what appears to be a gradual increase in absorption. In other words, a sloping base-line is observed.
