Novel applications of near-infrared spectroscopy of water and aqueous solutions from physical chemistry to analytical chemistry

Abstract

The results of many early investigations in physical chemistry have useful implications in present day analytical chemistry. Optical spectroscopy was one of the major tools used to elucidate structures and physical/ chemical properties of water and aqueous solutions by physical chemists. Recently, similar spectroscopic techniques have been used to solve analytical problems. For example, near-IR spectra of water and aqueous solutions have been used for the determinations of temperature, concentrations of electrolytes, and physical and chemical properties. Interdisciplinary investigations can be very productive and can benefit from previous knowledge in other disciplines.
