The UV-Visible spectra of MB33 in all mixtures investigated display three absorption bands in 50% ethanol within all the pH ranges 1.5-13.3 using Thiel buffer the maximum absorption of these bands is located at 438, 453 and a double head band at 410 and 475 nm . The band at 438 nm corresponds to absorption attributed to the cationic form (LH6) of MB33 (whereas L indicates to the parent structure of ligand without hydrogen protons) and disappears at pH > 3.0. The band at 453 nm corresponds to the absorption of the neutral form of the reagent (LH5-). The double head bands at 410 and 475 nm correspond to the di-anionic (LH42−) of MB33.〔M. M. Seleim, M. S.
