Maksyutenko, PavloRizzo, Thomas R.Boyarkin, Oleg V.2006-10-172006-10-172006-10-17200610.1063/1.2387163https://infoscience.epfl.ch/handle/20.500.14299/235225WOS:000242002400001We have performed a direct measurement of one of the most fundamental thermochemical values: the O-H bond energy in water. Using a triple-resonance laser excitation scheme, we excite the molecule through a series of vibrational overtone transitions to access directly the onset of the dissociative continuum. The disociation energy obtained from our experiments, 41145.94±0.15 cm-1, is ~30 times more accurate than the currently accepted value and has important implications for other thermochemical quantities linked to the bond energy of water.waterbond energyovertone spectroscopythermochemistrytext::journal::journal article::research article
