D-C[H.sub.3] peak at 438.27 is red-shifted by 6.28 nm compared to the D peak at 432 nm, which indicate that the introduction of methyl chain on the thiophene donor is very important for improved the red-shift absorption spectrum and also increase the molar extinction coefficient
(Table 3) at the maximum absorption wavelength compared to D.
A molar extinction coefficient
of 1310 [M.sup.-1] [cm.sup.-1] was used for the enzyme activity calculation, expressed in kilo unit per liter.
In the presence of PEG, there is an increase in the molar extinction coefficient
as compared to the value determined for the dye in aqueous solution (about 31600 [M.sup.-1] [cm.sup.-1]): the value for PEG-400 (400 mg/mL) is about 35800 [M.sup.-1] [cm.sup.-1] and that for PEG-12000 (400 mg/mL) is about 36100 [M.sup.-1] [cm.sup.-1].

The molar extinction coefficient
for this band decreases upon increasing concentration and is accompanied with increasing intensity of the long-wavelength band which becomes dominant at high ([10.sup.-4] M) concentrations (Figure 5(a)).
As expected, the 360 nmUV molar extinction coefficients
are very similar across all analyzed carbonyl-dinitrophenylhydrazine derivatives .
Given that the CV-dye exhibits a high molar extinction coefficient
at the implemented laser excitation wavelength ([[epsilon].sub.[lambda]] ~ 5 x [10.sup.4] [M.sup.-1] [m.sup.-1], @ [[lambda].sub.ex] = 532 nm), this dye can be properly implemented as an adequate absorber compound for photoacoustic experiments.
From above absorbances the standard absorptivity A (1% 1cm) and molar extinction coefficient
e were calculated which would be used to determine the drug content of dosage forms.
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.
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 absorbance of betacyanin solution at 538 nm was determined, and the betacyanin content in Portulaca oleracea seedlings was estimated using the molar extinction coefficient
for betanin of 65 x [10.sup.6] [cm.sup.2] [mol.sup.-1] (Schwartz and von Elbe 1980).
A is the absorbance, [epsilon] the molar extinction coefficient
, / the length of the measurement cell (in centimeters), and C is the concentration of the solution (in grams per liter).
This degradation product of T4 was shown to be the root cause of the failure of the FT4SS to pass retest/review specifications as per scp.99544 because the T4 degradation product exhibited significantly higher molar extinction coefficient
at 230 nm than T4 itself.
