Description
  • The isomers and conformers of four push-pull compounds: methyl-2-cyano-3-methoxyacrylate (MCMA) H(3)C-O-CH=C(CN)(COOCH(3)), methyl-2-cyano-3-aminoacrylate (MCAA) H(2)N-CH=C(CN)(COOCH(3)), methyl-2-cyano-3-methylaminoacrylate (MCMAA) H(3)C-NH-CH=C(CN)(COOCH(3)) and methyl-2-cyano-3-dimethylaminoacrylate (MCDMAA) (H(3)C)(2)N-CH=C(CN)(COOCH(3)) have been studied experimentally by vibrational and NMR spectroscopy and theoretically by the ab initio calculations at MP2 level in 6-311++G** basis set. The IR and Raman spectra of all compounds as a solid and solute in various solvents have been recorded in the region 4000-50 cm(-1). The NMR spectra were obtained in chloroform, acetonitrile and DMSO at room temperature.
