Despite being a simple and widely studied solution, a correlation between the structure and dynamics of the hydrogen bond (HBond) network in alcohol-water binary mixtures remains highly debatable. The present work combined Terahertz time domain spectroscopy (TTDS) and Terahertz-Fourier transform infrared (THz-FTIR) spectroscopy covering a wide frequency window of 0.3-18 THz, which probes most of the intermolecular roto-vibrational modes of water, to extract an extensive idea on such aspect of the binary mixtures. This study demonstrates a unified picture of the solute concentration-dependent HBond network structure and its associated dynamics in alcohol-water binary mixtures considering micro- and macro-scale (for partially water-soluble alcohols) phases present inside the systems. The work extensively took into account both the factors of hydrophobic chain length and macroscopic self …
