Phase transition chemical corrugation

For Cr =, capillary condensation shifts to a smaller value s 11.0, which is reasonable in view of the reduced net strength of attractive fluid substrate interactions compared with the previously discussed case. The shift of capillary condensation to lower substrate separation also persists for Cr = and Cr =, but it is much less pronounced, as Fig. 5.9 reveaJs. However, comparing only the latter two values of Cr. chemical corrugation of the substrate seems to be only of marginal importance for the location of the discontinuity (that is, the location of the phase transition) in the plot of p.
