Solvent and structural effects on the UV absorption spectra of N-(substituted phenyl)-2-cyanoacetamides

- Absorption spectra of selected cyano-acetamides were recorded in 16 solvents.
- Significant shift of the absorption maximum was detected only in DMSO and DMF.
- The effects of solvent were interpreted by Kamlet-Taft LSER concept.
- The effects of substituent were interpreted by Hammett substituent constant.
- The experimental results were interpreted with ab initio method MO calculation.
