WebHuckel Rule of Aromaticity (4n+2) Pi Electron Rule. Huckel's rule stated mathematically says that all planar aromatic compounds must have 4n+2 pi-electrons where n is a positive integer or zero (i.e. n= 0, 1, 2, 3…etc.). Aromatic compounds are comparatively stable due to the presence of resonance energy and delocalized electron clouds. WebJan 30, 2024 · Using this equation as an example to explain fluorescence, a high fluorescence rate (k f) value and low values of the all the other relative rate constant terms (k f +k i +k ec +k ic +k pd +k d) will give a large \( \phi \), which suggest that fluorescence is enhanced. The magnitudes of kf , kd, and kpd depend on the chemical structure, while ...
