    "abstract": "A model of rods with heads of variable size, which are confined to a planar\nsurface, is used to study the influence of the head group size on tilted phases\nin Langmuir monolayers. Simple free energy considerations as well as exact zero\ntemperature calculations indicate that molecules with small head groups tilt\ntowards next nearest neighbors, and molecules with larger head groups towards\nnearest neighbors. This provides a possible explanation for recent experimental\nresults, and for details of the generic phase diagram for fatty acid\nmonolayers.",
