“…Fluorescence measurements in matrices 20 and in the liquid phase [21][22][23] helped to identify the nature of the excited states undergoing ESIPT. Theoretical studies predicted a small 24 or nonexistent barrier 25,26 for the proton transfer and suggested similar reaction dynamics for many ESIPT systems.…”

“…The values of rate constants show that proton transfer is relatively faster in CMOH than in MFOH (11). However, the process is relatively slower than that observed in the case of other similar compounds such as methyl salicylate (MS) and orthohydroxybenzaldehyde (OHBA) (8,24,35). Slower decay rates indicate stronger interaction of CMOH with solvents compared to MS and OHBA.…”

“…Nagaoka et al (8) showed that this conversion is extremely slow in the case of o-hydroxyacetophenone (OHAP) and does not take place at all in the case of o-hydroxypropiophenone (OHPP), but occurs easily in the case of o-hydroxybenzaldehyde (OHBA) (8). The phosphorescence was also not observed in the case of methylsalicylate (MS) (33,38).…”
