Literary linguistics: Open Access research in English language

Strathprints makes available Open Access scholarly outputs by English Studies at Strathclyde. Particular research specialisms include literary linguistics, the study of literary texts using techniques drawn from linguistics and cognitive science.

The team also demonstrates research expertise in Renaissance studies, researching Renaissance literature, the history of ideas and language and cultural history. English hosts the Centre for Literature, Culture & Place which explores literature and its relationships with geography, space, landscape, travel, architecture, and the environment.

Abstract

The short intramolecular hydrogen bond in dibenzoylmethane has been studied by variable temperature neutron and X-ray single-crystal diffraction. Fourier difference maps have been used to image both the nuclear and electronic density of the hydrogen bond, in addition to determination of the refined positions obtained from the maxima of these densities. The nuclear density obtained from the neutron diffraction data shows an asymmetric position of the hydrogen atom in the hydrogen bond which is invariant as a function of temperature. The electronic density imaged from X-ray measurements, on the other hand, shows a migration of the bonding density from an asymmetric position at low temperatures to an almost centred position at room temperature.
