Аннотация: Two Ising models on a rectangular lattice (sigma(1) model and sigma(2) model) linked to three- and four-spin interactions are used to describe the sequence of tilted phase transitions in monolayers of amphiphilic long-chain molecules on an air-water surface. Starting from Morse atom-atom potentials self-consistent equations for basic thermal averages are derived in terms of a mean-field approximation. We employ the model for CH3(CH2)(18)COOH at two values of the molecule density and obtain all known tilted phases, including an intermediate one.
