1966Surface Sci. IV. 103 (heading) Ordered physisorbed layers on graphite. 1967Ibid. VI. 1 It has been argued that due to the weakness of physisorbing forces, the electron beam of the instrument would disturb the molecules significantly. Ibid. 2 Materials highly volatile at room temperature could not be physisorbed to concentrations approaching a monolayer. Ibid., A substance with a vapor pressure of 1 × 10-2 Torr or more will not physisorb on graphite in quantities approaching a monolayer if its ambient pressure over the graphite is 1 × 10-4 Torr or less. 1970C. Okkerse in B. G. Linsen Physical & Chem. Aspects Adsorbents & Catalysts v. 253 Wirzing suggested the use of the combination band of water at 5265 cm-1 for the quantitative determination of physisorbed water. 1971Sci. Amer. Dec. 51/1 A physisorbed species retains substantially its original structure. |
