The wetting of solid surfaces by gases and liquids is both fundamentally and technologically important especially in the areas of energy storage and conversion, e.g. catalysis. Our study proposes to determine the structure of solid monolayers of cyclohexane (C6H12) adsorbed on the surface of MgO and graphite, as a function of temperature. We have characterized the adsorption thermodynamics using adsorption isotherms and INS measurements of C6H12 using IN11 which suggest that a a high degree of translational rotation coupling takes pace in the fluid phase. Our companion molecular dynamic simulations reveal intriguing differences in the microscopic structure and dynamics suggesting that the subtle interplay between the molecule and substrate interaction strengths and the differences in symmetry may be responsible for the differences in the wetting properties.
