Actual Determination of Time-span in Absorption Spectroscopy and variation of absorbance vs.concentration is crucial in chemistry and biology. We investigated molecular absorption spectraof 1,4 -diamino anthraquinone taking concentration 20 − 90μM. We primarily report a violationand quantization of Absorbance in Beer’s Lambert Law and propose an alternative explanationfor the inherent phenomenon, quantum mechanically. Upon laser pulse excitation yielded photontransfer excited state having 17-96 attoseconds lifespan is formed for different concentrations ofsamples. We furnished a general equation for the electrostatic field, the wave function of photonsand its correlation with absorbance. Further, we propose an intricate relationship between theelectromagnetic field generated by particles and its wavefunction.
