Abstract
Molecular dynamics simulations of molten NaI have been performed using both rigid-ion and polarizable-ion models. The mass-, charge- and number-density autocorrelation functions have been calculated together with their frequency spectra. The liquid-state analogues of longitudinal optic and acoustic phonons are identified at longer wavelengths. The acoustic modes are weak and broad. The major differences between the rigid-ion model and the polarizable-ion model are thatKeywords
