摘要: Abstract We argue that the integrated intensity of interaction-induced depolarized light scattering is a sensitive indicator local environmental symmetry and we reach following conclusions. (1) The “cancellation effect” arising from cancellation two-body correlations by three- four-body can be cast in terms symmetry. (2) Interaction-induced intensities exhibit appreciable effects serve as (3) effect has usually been discussed density, simple relation between density assumed; however, molecular condensed phases small changes may accompanied large (4) lattice gas model quasi-continuum are not applicable for dense liquids because they cannot handle high packing imperfections which dominant factors determining liquids. (5) Short-range interactions, such electron overlap, orientational averaging anisotropic molecules lead to contributions largely due one- effects. These reduce sensitivity measured
