The hypothetical connection between liquid water and the two liquid phases: Low Density Liquid (LDL) and High Density Liquid (HDL) has been difficult to prove experimentally because of super-cooled water spontaneous freezing below the homogeneous nucleation temperature and amorphous ice crystallization at crystallization temperature. Here we are proposing the neutron scattering experiment which might allow us to get into HDL and LDL phases. The idea is to build on our previous experiments on SANDALS, RB1210380 and RB1320194 where it was shown that water in a cryo-vitrification solution forms nano-clusters confined into small volumes by the surrounding dynamic matrix of cryoprotectant solvents. These small volumes prevent the formation of crystalline ice because the water in them does not have enough time to relax and expand during cryogenic quenching.
