Vibrational relaxation in methanol-d, ethanol-d, and 1-propanol-d dissolved in CCl4 has been measured with ultrafast infrared pump-probe experiments. Non-hydrogen-bond donating OD stretches (similar to2690 cm(-1)) are excited. For concentrations less than or equal to2.5 mol %, alcohol monomers dominate the pump-probe signals, and all three alcohols yield monoexponential decays with decay times of similar to2 ps (varying somewhat for the different alcohols). In the 5 mol % samples studied, molecules associated with oligomers dominate the signals. The signals decay to negative values (increased absorption), but the rates of the vibrational excited state decays are unchanged from those observed in the 2.5 mol % samples. The negative signals recover on two time scales. We propose a model in which hydrogen bond dissociation, following vibrational relaxation, increases the concentration of non-hydrogen-bond donating hydroxyl groups and produces the observed negative signal. The observation of the same decay rates with and without hydrogen bond dissociation indicates that hydrogen bond breaking does not involve a new OD stretch relaxation pathway. Using a set of kinetic equations, the time constants for hydrogen bond dissociation and reformation have been determined to be 2-3 ps for breaking and roughly 20 ps and >10 ns for reformation. The fast recovering component of the negative signal reflects hydrogen bond reformation to an extent determined by a new local equilibrium temperature within the laser excitation volume. The slow recovering component reflects the slow diffusion of thermal energy out of the laser excitation volume.
