Elasticity of the spatial network of hydrogen bonds in liquids

A large body of experimental data on the isothermal compressibility of diamines, diols, amino alcohols, and light and heavy water obtained on a unique direct-compression setup was used to estimate the elasticity of the space network of hydrogen bonds of these substances. An inverse dependence of the modulus of all-round compression on a number of defects in the three-dimensional network was discovered. A comparison was made with the isothermal compressibility of liquids without the H-bond space network: liquid alkanes, aliphatic alcohols, benzene, and carbon tetrachloride.
