The pressure‐volume isotherm and x‐ray diffraction measurements for the coadsorption systems of krypton with methanol and ethanol on graphite have been carried out at 77 K. On graphite krypton and methanol are miscible while krypton and ethanol are immiscible. The two‐dimensional solid solution of krypton and methanol takes an incommensurate triangular structure with an intermolecular distance ∼4.10 Å and a molar composition Kr/CH3OH ∼0.6. Krypton adsorbed on top of the preadsorbed ethanol monolayer forms a triangular monolayer, incommensurate with the structure of the underlying monolayer.
