L. S. Dent Glasser, published in research papers as Lesley S. Dent Glasser, worked on crystallography, chemical transformations and science education. A 1968 paper with Ian B. Smith lists the Department of Chemistry at the University of Aberdeen and examines oriented transformations among manganese-containing solids.[ref]

Their observations connect chemistry with geometry: a reaction can preserve a relationship between the orientation of the starting crystal and that of the product, even while its composition changes. Where their results permitted an interpretation, the authors related the orientations to the oxygen framework and substantial movement of manganese. They also explicitly reported symmetry changes they could not explain. This makes the paper an example of using crystal structure to constrain a reaction mechanism without treating every structural observation as a completed explanation.[ref]

Her IUCr teaching pamphlet Symmetry by L. S. Dent Glasser develops the relation between finite-object symmetry, periodic arrays and space groups. Its examples show how repeating a motif introduces translations and combined operations beyond the symmetry of an isolated object.[ref]
