We study thermodynamic and dynamic properties of a rigid model of the fragileglass forming liquid orthoterphenyl. A system of N=343 molecules is consideredin a wide range of densities and temperatures, reaching simulation times up to1 microsecond. Working within the inherent structures thermodynamic formalism,we present results for the temperature and density dependence of the number,depth and shape of the basins of the potential energy surface. We evaluate theconfigurational entropy of the system and we study the connection betweenthermodynamical and dynamical properties. We confirm that the temperaturedependence of the configurational entropy and of the diffusion constant, aswell as the inverse of the characteristic structural relaxation time, arestrongly connected in supercooled states.Comment: RevTeX, 15 pages, 15 figure
