AN X-ray examination of hexa-methyl benzene, C6(CH3)6, recently completed, has led to certain definite and fundamental conclusions concerning the symmetry and form of the benzene ring. 
Structure Determinations of Increasing Complexity
I have had the opportunity of examining by X-rays the crystals of ergosterol and certain of its irradiation products, recently described by a team working at the National Institute for MedicalExpand
Peritectic phase transition of benzene and acetonitrile into a cocrystal relevant to Titan, Saturn's moon.
TLDR
The phase diagram of mixtures of acetonitrile and benzene is reported, and the stability of the structure under liquid ethane is tested, providing new insights into the structure and stability of potential extraterrestrial minerals. Expand
A Simple and Exact Interpretation of the Bond Lengths and Stacking Distances in Benzene and its Dimers in Terms of Atomic Covalent Radii
The structure of benzene and the stacking distances in its dimers have long been of interest for scientists. As the various rigorous approaches over the years to understand these have beenExpand
The thermochemistry and crystallography of the metal tris-acetylacetonates
Due to conflicting reports concerning the crystallographic properties of metal tris-acetylacetonates, we decided to explore the thermochemistry and crystallography of these substances to ascertainExpand

The associated magnetic moments of the periodic rotational motion of methyl groups in hexamethylbenzene (C6(CH3)6) were recently identified to contribute to its overall magnetic susceptibility. ThoseExpand
Origins and historical development of X-ray analysis
The article presents a brief account of the events leading to the discovery of X-ray diffraction in 1912. The early history and development of the science of X-ray analysis is then outlined and theExpand
Development of X-Ray Powder Diffraction Methods for Biomolecules
The comparable order of magnitude between interatomic distances in a crystal and the wavelength of X-rays make X-ray crystallography the ideal analytical tool to gain insight into the structure ofExpand
Problems of Organic Structures
In organic chemistry there are two basic and complementary problems, analysis and synthesis. By analysis the chemist attempts to find the number, kind and spatial arrangement of the atoms in hisExpand
Distortions, deviations and alternative facts: reliability in crystallography
TLDR
In this text based on the 2018 Lonsdale lecture, instructive examples are given of unusual and unexpected structures derived from X-ray crystallography, not all of which are genuine results. Expand
