  • Using femtosecond time-resolved heterodyne-detected vibrational sum-frequency generation spectroscopy the authors determine the vibrational relaxation (T1) time of the O-H stretch at the air/water interface by observing the decay of excited-state OH signals, providing a comprehensive picture of the interfacial vibrational relaxation process of water.

  • Optically stimulated vibrational control for materials has the potential to improve the performance of optoelectronic devices. The vibrational control of FAPbBr3 perovskite solar cells has been demonstrated, where the fast dynamics of coupling between cations and inorganic sublattice may suppress non-radiative recombinations in perovskites, leading to reduced voltage losses.

  • A fluorescent molecule is described that does not follow Hund’s rule and instead shows singlet and triplet excited states with inverted energy levels, leading to high-efficiency OLEDs with potential implications for optoelectronic devices.

  • Reactions at the interface between water and other phases play important roles in various chemical settings. Now, ultrafast phase-sensitive interface-selective vibrational spectroscopy has revealed that the photoionization of phenol can occur four orders of magnitude faster at the water surface than in the bulk aqueous phase.

  • Water’s hydrogen-bond network is truncated at hydrophobic interfaces and the dynamics of the resulting free OH groups is not well understood. The authors experimentally show that the main vibrational relaxation mechanism for free OH at the air-water interface is a diffusive molecular reorientation, rather than intramolecular energy transfer.
