We present the first observation of vibrational transitions in the [H<sub>3</sub>O]<sup>-</sup> anion, an intermediate in the anion-molecule reaction of water, H<sub>2</sub>O, and hydride, H<sup>-</sup>, using a laser-induced isotopic H/D exchange reaction action spectroscopy scheme applied to anions. The observed bands are assigned as the fundamental and first overtone of the H<sub>2</sub>O-H<sup>-</sup> vibrational stretching mode, based on anharmonic calculations within the vibrational pertur ...[more]
