5] were determined according to Omura and Sato [11], using molar extinction coefficient 91 [cm.
Calculations were made using a molar extinction coefficient of 9.
where A is the absorbance [dimensionless], [epsilon] is the specific molar extinction coefficient [l/mol m], b is the optical path [m], and c is the concentration [mol/l].
F]([lambda]) is the number of photons of fluorescence of wavelength [lambda] per second per nanometer, [epsilon] is the molar extinction coefficient ([m.
While, the molar extinction coefficient (e) of complex was calculated through plotting a working curve of absorbance as a function of concentration at lmax 522 nm by considering Beer- Lambert's law (A = e b c), where, A=absorbance of absorbing species, e = molar extinction coefficient, b=cell path length and c=concentration of absorbing species.
where A is the absorbance (dimensionless), [epsilon] is the specific molar extinction coefficient (l/mol m), b is the optical path (m) and c is the concentration (mol/l).
