The glacial geomorphology of part of the Western Grampians of Scotland, with especial reference to the limits of the Loch Lomond Advance
Published 1984“…The reconstructed form of the main ice mass indicates that it covered an area in excess of 2,000km (to the power of 2), that its total volume was ca. 460km (to the power of 3), and that maximum ice-shed altitudes of ca 700 - 750m O.D. were attained in the Glen Nevis-Rannoch Moor-Glen-Lyon areas. Equilibrium rim lines calculated for the main ice mass and for 17 independent corrie, valley and plateau glaciers indicate that firn lines rose from ca. 400m O.D. in the SW to +900m O.D. in the NE part of the study area. …”

In search of a new class of stable nitroxide: synthesis and reactivity of a peri-substituted N,N-bissulfonylhydroxylamine
Published 2011“…In an approach to stabilising a bissulfonylnitroxide radical, the cyclic, peri-substituted N,N-bissulfonylhydroxylamine, 2-hydroxynaphtho[1,8-de][1,3,2]dithiazine 1,1,3,3-tetraoxide (1), has been prepared by formal nitrogen insertion into the sulfur–sulfur bond of a sulfinylsulfone, naphtho[1,8-cd][1,2]dithiole 1,1,2-trioxide. The heterocyclic ring of 1 is shown to adopt a sofa conformation by X-ray crystallography, with a pseudo-axial hydroxyl group. …”
