What Nonlinear−IR Experiments Can Tell You about Water that the IR Spectrum Cannot
TL;DR: The results illustrate that the vibrational lifetimes and orientational relaxation time scales vary dramatically between the four samples and do not correlate with the amount of water relative to surfactant or solute in solution.

Water Dynamics in Polyacrylamide Hydrogels
TL;DR: Polymeric hydrogels have wide applications including electrophoresis, biocompatible materials, water superadsorbents, and contact lenses as discussed by the authors, but their properties involve the poorly characterize properties.

Abstract: measurements of the CO vibrational lifetime to yield the homogeneous pure dephasing. The homogeneous pure dephasing is the Fourier transform of the homogeneous line width with the lifetime contribution removed. The measurements were made from 60 to 300 K and show that the CO vibrational spectrum is inhomogeneously broadened at all temperatures studied. The mutant protein’s CO vibrational pure dephasing rate is 20% slower (narrower homogeneous pure dephasing line width) than the wild-type protein at all temperatures, although the only difference between the two proteins is the replacement of the wild-type’s polar distal histidine amino acid by a nonpolar valine. These results provide insights into the mechanisms of the transmission of protein fluctuations to the CO ligand bound at the active site, and they are consistent with previously proposed mechanisms of protein-ligand coupling.
Vibrational relaxation of the free terminal hydroxyl stretch in methanol oligomers: Indirect pathway to hydrogen bond breaking
TL;DR: In this paper, the authors investigated the vibrational relaxation of methanol-d (MeOD) in carbon tetrachloride via ultrafast infrared pump-probe experiments.
Multilevel vibrational dephasing and vibrational anharmonicity from infrared photon echo beats
TL;DR: In this article, a vibrational photon echo experiment was performed on the asymmetric CO stretching mode of tungsten hexacarbonyl in glassy dibutylphthalate as a function of temperature using sub-picosecond infrared pulses (1976 cm −1 ) from a free electron laser.
