Abstrakt: Low frequency Raman spectra (20–400 cm-1) are presented of formamide dissolved in dimethylsulfoxide (DMSO). The concentration of formamide ranges from 2%–75% (v/v). The two formamide bands at 110 and 190 cm-1 in the neat liquid exhibit only smaller frequency shifts upon dilution. The intensities of both bands are proportional to the concentration of formamide. The conclusion is, that the linear chain structure, found in neat liquid formamide, is conserved in the DMSO solution. Raman spectra of the NH-stretching region (2950–3500 cm-1) confirm this hypothesis. [ABSTRACT FROM AUTHOR]
