H₂O₂‐induced hydrogen bond water networks enhanced on stimulated Raman scattering

Abstract

Forward stimulated Raman scattering in pure water and H2O2–H2O mixture solutions are investigated under different pump laser energies. Three characteristic peaks are observed in mixture solutions due to the enhancement of hydrogen bonds (H‐bonds) structure of water molecules by H2O2. Simultaneously, stimulated Raman scattering lines indicate that high‐pressure ice‐phase is formed in mixture solutions, which is attributed to the reduction of the laser breakdown threshold of liquid water by H2O2, resulting in a strong dynamic high pressure.

“…The application of this new approach to SRS microscopy allows greater insight into deep‐lying structures in a noninvasive way. Wang et al [ 111 ] demonstrated the coexistence of ice‐like and quartz‐like structure in localized liquid water by stimulated Raman scattering. The two structures show different pressure‐dependent behaviors based on the SRS results; meanwhile, the distribution of two structures is different in the bulk and on the surface of water.…”
