!--[if gte mso 9]> 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 measured with pump probe picosecond experiments and are all very short (35 ± 5) ps as compared to other substituted phenols.       The electronic states and active vibrational modes of the cis and trans
