Vibrational relaxation of the H2O bending mode in liquid water
Abstract
We have studied the vibrational relaxation of the H2O bending mode in an H2O:HDO:D2O isotopic mixture using infrared pump-probe spectroscopy. The transient spectrum and its delay dependence reveal an anharmonic shift of 55±10 cm-1 for the H2O bending mode, and a value of 400±30 fs for its vibrational lifetime.
