title: Two distinct raman profiles of glassy dilute LiCl solution
abstract: We make glass of dilute LiCl aqueous solution by cooling micrometer-sized droplets of the solution extremely quickly and measure the Raman spectra of the glass. It is found that the OH stretching vibration mode of the glass of dilute solution is composed of the OH stretching vibration mode of pure glassy water and that of the glass of solvent water in the highly concentrated solution. This is consistent with the possibility of the existence of two distinct glassy states of water in dilute LiCL solution at low temperature.
