摘要: We present microscopic equations for the rigidity constants of a simple liquid–vapor interface. These expressions are analogous to Kirkwood–Buff formula surface tension. The calculated using an approximate expression density auto correlation function in interface near critical point. This results k=0.631 kBTc and k=0.239 kBTc.
