Extensive Research have been conducted as protonated aqueous solutions, H-X (X=I, Cl, Br) are universally vital in areas ranging from biochemistry to pharmaceutical sciences. However, the interactions between H+ protons and X- anions remains unsolved. Fourier Transform Infrared Spectroscopy (FTIR) is a technique to obtain high-spectral resolution data infrared spectrum of absorption, emission, photoconductivity or Raman Scattering of Solid, Liquid and gas over a wide spectral range. Absorption of water is being measured in terms of wavenumber (cm-1). Relaxation of O:H bonds and H-O stretching phonons can be measured through FTIR absorption spectroscopy with frequency ranging from 400 to 4000cm-1. In HCl solvation, Differential Phonon Spectrometrics (DPS) can provide information in fluctuations, frequency shifting and peak area of H-O bonds. This is crucial in displaying disrupted solution surface stress caused by the H+<->H+ fragilization.
