Photochem Photobiol Sci. 2013 Feb;12(2):246-53. doi: 10.1039/c2pp25190f. Epub 2012 Sep 6.The photophysical properties of menthyl anthranilate (MA), a UV-A absorber, have been studied through measurements of UV absorption, fluorescence, triplet-triplet absorption and time-resolved thermal lens in ethanol at room temperature and/or 77 K. The phosphorescence and time-resolved electron paramagnetic resonance spectra have also been observed in ethanol at 77 K. The energy levels of the lowest excited singlet (S(1)) state and triplet (T(1)) state were determined. Read More
