The
extinction coefficient can be obtained from the following relation [18]:
Hence three replicates of five serial dilutions were used to determine standard absorptivity [A (1% 1cm)] and molar
extinction coefficient () which were found to be 285.90 dl/g/cm and 7370.62 per Mol/cm respectively (Table 2).
The new
extinction coefficient [k.sup.*.sub.i] at changed thickness [d.sup.*] is
It is seen that the gravitational field shielding by scalar field is undetectable in a laboratory experiment since the
extinction coefficient is very small for an object with laboratory scale size.
The molar
extinction coefficient of the SGY-145 was found for both the concentrations i.e., C1=1070 umol/L and C2=535 umol /L and is shown in the Table 3.
7 shows the velocity profiles for various values of effective
extinction coefficient of porous medium and Pr numbers.
This quantity was designated as the relative fog density d*, which is proportional to the
extinction coefficient. Such an approach is reasonable provided that the distances the light passes within the detector are much smaller than the inverse
extinction coefficient (this condition was held in our experiment).
For comparison, the graphs presenting CO concentration and
extinction coefficient obtained during the combustion of the same type of specimens without piloted ignition are given in Figs.
The difference between the two values is minimized until a best solution is achieved for the refractive index n, the
extinction coefficient k, and the film thickness d.
As seen, the shape of the absorption spectrum of PPME resembles that of PPa with two strong absorption vibronic bands centered at 412.5 nm (belongs to B band) with molar
extinction coefficient of [epsilon]412.5nm = 1.15 x [10.sup.5] [M.sup.-1] [cm.sup.-1] and at 666.8 nm (belongs to Q bands) with molar
extinction coefficient of [epsilon]666.8nm = 4.96 x [10.sup.4] [M.sup.-1] [cm.sup.-1].
The visibility at a point is the distance that a person could see if he or she were in a space with smoke that had the same
extinction coefficient as at the point.
