Water is abundant and it covers about 70 per cent of earth’s surface. However, it is the least known due to its unusual behaviors. The study of the mysteries of water is essential to provide us with more knowledge on it as water is plays a very important part in our life. The odd behaviors are said to be due to the hydrogen bonds of water. Water is a universal solvent. This is because it can readily dissolve ionic compounds and polar molecules. Fourier Transform Infrared Spectroscopy (FTIR) is a technique used based on the fundamental principles of molecular spectroscopy to obtain an infrared spectrum of absorption, emission, photoconductivity or Raman scattering of a matter in the form of solid, liquid or gas. The absorption of water is measured in terms of wavenumber (cm-1). FTIR absorption spectroscopy can also measure the relaxation of O:H bonding and H-O stretching phonons in the frequency range from 400 to 4000cm-1.
