Raman and infrared spectroscopies are used as local probes to study the dynamics of the Nd-O bonds in the weakly multiferroic ${\mathrm{NdMn}}_{2}{\mathrm{O}}_{5}$ system. The temperature dependence of selected Raman excitations reveals the splitting of the Nd-O bonds in \${\mathrm{NdMn}}_{2}{\mathrm...
