The most prominent electronic transitions of the molecule according to oscillator strength
in gas phase, acetone, DMSO, dichloromethane and hexane have been evaluated in Fig.
where c is the speed of light, f is the oscillator strength
, e is the fluorescent energy, and u is a constant.
where f is the oscillator strength
of the dye molecules; a large oscillator strength
can contribute to the improvement of LHE.
Essential parameters have been considered as heat during formation, frontier energy gap, dipole moment, and oscillator strength
. Such parameters were intended due to their convinced impact in stability differentiation between all possible outputs .
This lowest energy transitions are dominated by ligand-to-ligand charge transfer (LLCT) with some admixture of metal-to-ligand charge transfer (MLCT) and exhibit much smaller oscillator strength
as compared to the main band.
In formula (1), [f.sub.0] represents the oscillator strength
(weight factor) and the plasma frequency [[omega].sub.p] is associated with intraband transitions (free-electron transitions) and is a function of electron density and mass which are given in Palik's Handbook of Optical Constants .
Main excitation energy [wavdength (nm) and calculated energy (cV)], oscillator strength
(f) and their corresponding configuration of PFBT and PCzBT (H.
The weighted oscillator strength
(or gf value) is like the line strength between two levels,
Let the absolute value of the oscillator strength
at yield be [F.sub.y], and let k denote the oscillator stiffness in the elastic range.
It is more convenient to express of the differential cross section in terms of a quantity known as the Generalized Oscillator Strength
, F (q, [epsilon]) defined by
When you generate the charged states that give rise to conductivity, you also change the oscillator strength
of the polymer within the visible range of the spectrum.
The summarized data including wavelength absorption, oscillator strength
, light harvesting efficiency and molar extinction coefficient are shown in Table 3.
