Question
For the dye 1,1'-Diethyl-2,2-carbocyanine iodide:
gamo,
CH₂
The use of the PIB theory indicates that the lowest energy of electronic transition between HOMO and LUMO orbitals is given by
h² (P+4)
he
h²
ΔΕ
(N+1) amle (P+3)²
8mL2
Assuming the value of lcc = 149 pm, what would be the estimated wavelength of the energy of excitation needed to promote an electron from the
HOMO electrons to the LUMO orbital?
[c= 2.98 x 10 m/s, h = 6.626 x 10¹/s, and m= 9.109 x 10-¹¹ kg]
