Abstract

The IR and Raman spectra of aminomethylene-malonic acid dimethylester (AMDME)[NH2CHC (COOCH3) 2] and its N-methyl derivatives (MAMDME and DMAMDME) were measured in solid phase and in different solvents at various temperatures. X-ray analysis revealed that AMDME exists in solid phase as EZ conformer, MAMDME as ZZa conformer and DMAMDME as ZE conformer (the first and second E or Z letters express the ...
