Linear solvation energy relationships. Part 3. Some reinterpretations of solvent effects based on correlations with solvent π* and α values

摘要: Solvent polarity and hydrogen bonding effects on a number of physical chemical properties reaction parameters are unravelled rationalized by means the solvatochromic comparison method equations form XYZ=XYZ0+sπ*+aα, where π* is measure solvent α bond donor acidity. XYZ's considered include ET values for eight electronic spectral transitions, two sets nitrogen hyperfine splitting constants, set fluorescence lifetimes, logarithms rate constants four nucleophilic substitution reactions, ‘electrophilicity parameter,’E, Koppel Palm.
