Abstract One of the original structural studies on Langmuir-Blodgett (LB) multilayers of 22-tricosenoic acid using the technique of reflection high-energy electron diffraction was performed by Peterson and Russell (1984, Phil. Mag. A, 49, 463). In their paper, four distinct structural arrangements of the long-chain fatty acid were identified, where the arrangement adopted by a particular sample was found to depend on the substrate and deposition conditions. The identification of the C2 H4 subcells in each of these arrangements was made on the basis of a number of assumptions, some of which have subsequently been shown to be erroneous. In particular, the identification of a triclinic subcell appears to be in error and diffraction patterns to which triclinic subcells have been assigned may be re-interpreted as arising from close-packed structures with monoclinic or orthorhombic subcell arrangements.
