Hydrogen bonding parameter correlations

This correlation was also supported by independent calculations relating to the structure of the liquids in the surface which yielded essentially the same constant 0.0715. It is noteworthy that the polar and hydrogen bonding parameters are weighted with the same coefficient. This is the same situation as for correlating the solubility, swelling, etc., data as discussed above. 

Eq. (3.23) the geometrical hydrogen bonding parameters for the ions that describe their effects on the structure of the water. These may be taken for correlations with other quantities that describe the water structural effects of ions that are better established, such as Bi, and Astruc-5. The resulting expressions, calculated with = — 929 J mor are ... 

The swelling, crazing, and cracking behavior of PMMA, PVC, and PSU in contact with some 70 different liquids was analyzed by Vincent and Raha [123]. They considered not only the solubility parameter 65 but also the value of the hydrogen bonding parameter Hqd based on the displacement of the OD infra-red absorption band in CH3OD in presence of the particular liquid and benzene. Better (but still no unique), correlation between the mode of failure and 63 and Hqd was obtained. 

Studies by the group directed by Mayoral have been limited to Diels-Alder reactions of type A. When water was not included, the rate constants correlate with the solvent hydrogen-bond-donating capacity Upon inclusion of water the solvophobidty parameter, Sp, contributed significantly in... 

The correlation of Snyder s solvent strength e° with molecular dipolarity and polarizability (7t ) and the hydrogen-bond acidity (a) and the hydrogen-bond basicity ((3) solvatochromic parameters for adsorption chromatography can be achieved, although most papers on solvatochromic parameters deal with reversed-phase systems [18].
