Details of the
SPP solubility parameters
(Solvent Polarity/Polarizability), together with a more comprehensive list and
a discussion on solvent scales in general can be
found at the
→web site of Prof. Catalán (archived version).
The Solvent acidity (SA) parameter is correlated with
→Dimroth-Reichardt ET (
→ET vs SA),
→Gutmann AN (
→AN vs SA) and
→Swain Acity (
→Acity vs SA).
The Solvent basicity (SB) parameter is correlated with
→Gutmann DN (
→DN vs SB).
