Abstract
The solvatochromic comparison method is used to unravel solvent polarity and hydrogen bonding effects on a variety of NMR spectral shifts and coupling constants. Solvent effects are rationalized in terms of the solvatochromic parameters π*, δ, α and β. Properties analyzed include ^19^F shifts of 5‐fluoroindole, ^1^H shifts of fluorodinitromethane, tert‐butanol, phenol, 2‐methylbut‐1‐en‐3‐yne, and thioacetamide, ^1^H and ^13^C shifts and J(^13^C^1^H) coupling constants of chloroform, ^13^C shifts of acetone, ^15^N shifts of pyridine, ^15^N and ^29^Si shifts of 1‐methylsilatrane, and some J(^119^Sn,C,^19^F) coupling constants of polyalkyltin compounds.
