For structural determination of molten salts, X- ray and neutron diffractions are the most powerful methods. Computer simulations represented by Monte Carlo and molecular dynamics methods have become more and more useful for analysing the experimental data. Particularly, 3-dimensional structure which could not be obtained by diffraction experiments alone is easily deduced with the help of the simulations. Recent studies on molten CsCl mainly by McGreevy's group and on molten LiNO3 and RbNO3 by the author's group are introduced as examples, in which diffraction experiments and computer simulations are combined for the structural analyses.
