TL;DR: In this article, the authors reviewed the results and discussions associated with stepwise and concerted mechanism controversy on ESDPT of 7AI 2 together with the excited-state dynamics associated with ESDPTs.

TL;DR: The observed decay profiles of 7AI2 by exciting the origin and the intermolecular stretch fundamental in the S1 state are well reproduced by single-exponential functions with time constants of 1.9 +/- 0.9 ps and 860 +/- 300 fs, respectively, which provides clear evidence of the concerted mechanism of ESDPT in 7 AI2.

TL;DR: In this article, the laser induced fluorescence and dispersed fluorescence spectra of jet-cooled N-salicylideneaniline were observed in a supersonic free jet for the first time.

TL;DR: The observed H/D kinetic isotope effects imply that the ESDPT reaction of 7AI2 has a "cooperative" nature; i.e., the motion of the two moving protons strongly couples each other through the electron motions.

TL;DR: The results suggest that the ESTPT/HT reaction in 7AI(CH(3)OH)2-d(0) directly proceeds from the photoexcited states with the internal energy less than approximately 600 cm(-1), but it occurs from the isoenergetically vibrational-energy redistributed states when theinternal energy is large.
