The papers of William Price, chiefly relating to spectroscopic analysis and photoionisation, comprise correspondence, lecture and teaching notes, notes compiled while reviewing scientific articles, original research notes, papers concerning Price's employment as an examiner, obituaries and reprints of journal articles, 1929-1993. These notably include correspondence with colleagues describing projects and experiments and sharing observations and data, 1942-1990; lecture notes and teaching papers compiled by Price on the theory of spectroscopy, theoretical and applied optics, especially microscopy, basic molecular chemistry, electron configurations and bond and dissociation energies of molecules, 1948-1978; notes compiled by Price for the peer review of articles and on Price's own published articles, including on the spectra of halogens, the structure of polyatomic molecules, on water and hydrides, the calculation of ionisation potentials, benzenes and hydrocarbons, the structure of the DNA molecule and natural fibres such as keratin, 1929-1977; original research notes on spectroscopic analysis, especially ultraviolet spectra of rare gases, ethylene, sulphur dioxide and other compounds, 1933-1986; papers relating to Price's work as an examiner including draft and complete examination question papers and correspondence, 1952-1978; papers concerning the membership by Price of various learned societies and attendance at scientific conferences and symposia, 1940-1992; obituaries and newspaper cuttings on Price and other distinguished scientists, 1976-1993; typescript copies and reprints of scientific journals containing articles by Price and others, on topics including spectroscopy, photoionization, ionisation potentials and electron configuration and bond and dissociation energies, 1945-1990.

Papers of Colin William Fraser McClare, c1957-1981, comprising biographical and autobiographical material; laboratory notebooks c1964-1976; 'ideas' diaries; drafts for lectures and papers (not all published) c1959-c1976; teaching material, in particular for a course on the 'Social Impact of the Biosciences' which started in 1973, with which McClare had been closely involved; a set of McClare's publications including his major papers on bioenergetics and the correspondence arising; correspondence, 1964-1976 (mainly early 1970s), includes letters exchanged with the philosopher Sir Karl Raimund Popper, who offered considerable encouragement to McClare's early attempts to formulate and publish his scientific ideas, and whose philosophy McClare acknowledged as a profound influence.
