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.
