In an investigation of methylene replacement by small heteroatom insertions the crystal structures of N,N-dioctadecylamine, (C18H37)2NH, and dihexadecyl ether, (C16H33)2O, were determined by electron crystallography and infrared spectroscopy. Crystal

The orthorhombic crystal packing of 15-trans-triacontene was determined from electron diffraction intensities observed from epitaxially oriented and from solution-grown samples and by infrared spectroscopy of melt-crystallized thin layers. As determi

X-ray diffraction studies of ammonium myristate and palmitate show crystals that belong to space group P21/n with the methylene groups packing in a triclinic subcell. The infrared spectra of the palmitate and stearate are similar as expected, but the

An equimolar combination of n-C28H58/n-C32H66/n-C36H74, crystallized from the melt, initially forms a solid solution. Electron diffraction data from the epitaxially oriented [100] projection can be used to determine its crystal structure, a pseudo n-
