Proton transfer in the ground and excited states of 4-methyl-2,6-diformylphenol (MFOH) in ethanol/water, ethanol/metha-no1 and ethanol/dioxane solvent mixtures has been studied using steady state and nanosecond transient emission spectroscopy. The lifetime is not affected much in water/alcohol mixtu

The ground and excited state proton transfer reactions of 4-methyl-2,6-dicarbomethoxyphenol (CMOH) have been studied in water and some alcoholic solvents both in the presence and in the absence of base by means of absorption, emission, and nanosecond spectroscopy at room temperature and 77 K.

Proton translocation in the singlet excited state of 4-methyl-2,6-diformyl phenol (MFOH) results in an interesting fluorescence band at 535 nm. The fluorescence emission and excitation spectra of MFOH are recorded and a time-correlated single-photon counting technique is used to determine the fluore
