Abstract The dynamic structure factor of dense two‐component plasmas is studied within the method of moments. A new model for the Nevanlinna parameter function is suggested. Our results on the dynamic structure factor satisfy the sum rules and other exact relations automatically, independently of the choice of a mathematically consistent model of the latter. A quantitative agreement is obtained with the molecular dynamics simulation data. Our approach permits to correct and complement the results of alternative approaches.
