19. Analysis of other infrared active vibrations also indicated large kinetically stable deviations from isotropy. Dichroism of the asymmetric methyl stretch is not directly linked to backbone orientation.
20. The distribution calculations are made on the hypothesis of total conformational stability. Figure 1 shows that this is correct at the earlier stage of adsorption, when polymers have the opportunity to arrange many surface-segment contacts, so the structure is frozen. It is true that chains deposited at very high surface coverage have fewer surface contacts, and such loosely bound polymers might experience exchange between bound and loop portions, but this does not affect the conclusion as to bimodality.
