Abstract :
Transient infrared absorption of diluted HDO/D2O solutions is measured with 150 fs laser pulses. The signal intensity decays in a heavily non-exponential way, and its variation is often non-monotonic; no quantum beats are observed. These effects are ascribed to the simultaneous presence of solvent and population dynamics in low lying vibrational states, and to a partial cancellation of the bleach and absorption intensities.
