The truth being that when Planck placed two materials together, the bounding element, da, must be characterized on one side by the reflectivity and aborptivity of the first material and on the other side, by the reflectivity and absorptivity
of the second material.
where [alpha] is the absorptivity
, R is the reflectance, and t is the transmittance of the surface.
092 (a) = Calculated from Beer-Lamberts Law using the absorbances at 450 nm and molar absorptivity
The values for the attenuation coefficient and absorptivity
are shown in Tables 1-3 and the graphs are shown in Figs.
In Table 4 the absorptivity
test results of the mortars are presented.
UV-vis absorption maxima and absorptivity
(in parentheses) (a)) and (29) Si NMR chemical shifts for unsaturated silicon nuclei of tetrasilyldimetallenes Compound [[lambda].
Absorbance scans for dilutions of each new bilirubin stock in 10 mmol/L NaOH revealed an absorbance peak at 440 nm and a mean absorptivity
of 54 958 mol/[L.
Kirchoff's Law is valid so that the emissivity [epsilon] and absorptivity
ct of the surface are the same.
Although the menu items were descriptive, the actual data for each element (mass, R-values, surface absorptivity
Usually, the MRT is measured with a globe thermometer, that is dry bulb thermometer inserted in matte-black copper sphere with 150 mm diameter and absorptivity
that is close to the skin absorptivity
(ISO 7726, 1998).
At the optimum experimental conditions of the reaction of the reagent HOTT with mercury (II) in the aqueous solution of pH 4-6, the effective molar absorptivity
([epsilon]) calculated from Beer's-Lambert plot and the Sandell's sensitivity index  of the mercury (II)-complex with and without the use of [beta]-correction spectrophotometry were found to be 4.
In the nearIR, for example, molar absorptivity
is quite low compared to higher IR wavelengths.
