“…We have now traced this to what we believe to be the inaccurate cell parameters used by Hayashida. Table 1 shows that the cell parameters given by M & L for C18Has and those given by Crissman et al (1970) for C20H42 agree better with each other (apart from fl) than with the parameters obtained from Hayashida's cell after reduction. Accordingly, we have used the M & L parameters transformed to the system used by Hayashida (V, Table 1).…”

Owing to a mis-indexing of the Okl zone, the triclinic cell proposed by Hayashida (J. Phys. Soc. Japan (1962), 17, 306) for octadecane, CIsH3s, is not correct: nor therefore is the structure proposed by him. The error has been corrected and the structure refined from Hayashida's hOl and Okl data. Even after correction, the structure showed some minor anomalies. These we believe are due to inaccuracies in Hayashida's triclinic cell parameters. Good results are obtained using the cell originally proposed by MiJller & Lonsdale (Acta Cryst. (1948), 1, 127), suitably transformed to suit the axial system used by Hayashida, namely, a = 4"28s, b = 4"820, c = 24"898 A, ~ = 85.150, fl= 67.8 and y = 72"70L Space group PI.

“…The headgroup of the DTS has an electron density of 0.476 ± 0.007Å −3 , compared to 0.532 ± 0.004Å −3 in the case of the OTS. Likewise, the density of the DTS tail (0.82 ± 0.01 g/cm 3 ) corresponds to 88% of an alkane crystal's density [28], whereas the OTS reaches 100% (0.936 ± 0.004 g/cm 3 ). This difference is also observed when comparing the thicknesses of the layers with the calculated length of an all-trans hydrocarbon chain [26].…”

Solid surface structure affects liquid order at the polystyrene–self-assembled-monolayer interface

We present a combined x-ray and neutron reflectivity study characterizing the interface between polystyrene (PS) and silanized surfaces. Motivated by the large difference in slip velocity of PS on top of dodecyl-trichlorosilane (DTS) and octadecyl-trichlorosilane (OTS) found in previous studies, these two systems were chosen for the present investigation. The results reveal the molecular conformation of PS on silanized silicon. Differences in the molecular tilt of OTS and DTS are replicated by the adjacent phenyl rings of the PS. We discuss our findings in terms of a potential link between the microscopic interfacial structure and dynamic properties of polymeric liquids at interfaces.
