Abstract

A simplified dimensionless method was constructed to characterize the phase transition between water and ice based on Raman spectrum (RS) without contact testing samples. This method reduces the requirement of the spectrum intensity, simplifies the complex mathematical analysis and improves the resolution of detection which only depends on the relative intensity of RS. The current work establishes an important tool for accurate characterization of RS so that it could better interpret various phase transition mechanisms of water and aqueous solutions.
