SummaryA 19-year-old woman was diagnosed with osteogenesis imperfecta (OI). She had sustained numerous low-trauma fractures throughout her childhood, including a recent pelvic fracture (superior and inferior ramus) following a low-impact fall. She ha

This article describes studies on oxidative-photodegradation of cured Epolite epoxy resin using techniques of IR spectroscopy with attenuated total reflectance optics and scanning electron microscopy. The results show that the oxidative-photodegradat

The infra-red spectra of methyl-fluoroformate, -cyanoformate and -propiolate have been recorded between 4000 and 50 cm–1. All normal vibrations (including torsional modes) for these substances have been tentatively assigned to observed absorption b

The stable molecular conformations of methyl-fluoroformate, -propiolate, -cyanoformate, -acrylate (cis) and -acetate have been shown to be planar, and for the latter four compounds the cis ester molecular skeleton has been established. Barriers to in

This review covers most of the work carried out on the determination of molecular structure and conformation of carboxylic esters and simple derivatives in the vapour and liquid phases together with spectroscopic studies of the solid state. A brief s

EVIDENCE for cis–trans isomerism of the conjugated systems of molecules with bond-structures analogous to that of butadiene has frequently been sought (refs. 1 and 2 summarize earlier work), but it is often difficult to establish its occurrence. Th

THE rotation spectra of ethyl derivatives continue to be of interest for determining structure parameters and. the force field of these molecules1–5. We have measured the rotation spectra of two further members of this series, ethyl acetylene and e
