Fast Nonradiative Decay in o-Aminophenol [PDF]
The Journal of Physical Chemistry A, 2014 The gas phase structure of 2-aminophenol has been investigated using UV-UV as well as IR-UV hole burning spectroscopy. The presence of a free OH vibration in the IR spectrum rules out the contribution of the cis isomer, which is expected to have an intramolecular H-bond, to the spectra. The excited state lifetimes of different vibronic levels have been
