A molecular dynamics simulations study on the behavior of liquid N-methylacetamide in presence of NaCl: Structure, dynamics and H-bond properties

► Addition of a small amount of NaCl facilitates the structural breaking of NMA. ► Slower dynamics is observed in the solution with increasing NaCl concentrations. ► Initially, residence time of 'O' of NMA near Na+ is increased with ion concentration. ► Whereas the H-bond structural relaxation between ONMA..HNMA and Cl-..HNMA is decreased.
