Electronic transitions and the high pressure chemistry and physics of solids by H. G Drickamer( Book )

11 editions published between 1973 and 2013 in English and held by 361 WorldCat member libraries worldwide

There is no paucity of books on high pressure. Beginning with P.W. Bridgman's The Physics of High Pressure, books of general interest include the two-volume Physics and Chemistry of High Pressure, edited by R.S. Bradley, and the series, Advances in High Pressure Research, as well as the report on the Lake George Conference in 1960. Solid state physics is well represented by Solids Under Pressure, edited by Paul and Warschauer, by Physics of Solids at High Pressure, edited by Tomizuka and Emrick, and by Properties Physiques des Solides sous Pression, edited by Bloch, as well as by chapters in Volumes 6, 13, 17, and 19 of Solid State Physics, edited by Seitz, Turnbull, and Ehrenreich. Chemistry in gases and liquids is covered in Weale's Chemical Reactions at High Pressure, and Hamann's Physico-chemical Effects of Pressure. In addition to the coverage of techniques and calibrations in the above volumes, Modern Very High Pressure Techniques, edited by Wentorf, High Pressure Methods in Solid State Research, by C.C. Bradley, The Accurate Characterization of the High Pressure Environment, edited by E.C. Lloyd, and a chapter in Volume 11 of Solid State Physics are devoted entirely to this facet of high pressure research. It is not our plan either to supersede or extend these approaches. It is our purpose here to discuss the effect of high pressure on the electronic properties of solids

The Effect of Pressure on the Fluorescence of 9-Carbonyl Substituted Anthracenes( Book )

1 edition published in 1976 in English and held by 1 WorldCat member library worldwide

The pressure dependence of the fluorescence intensity of 9-anthraldehyde, 9-acetylanthracene and 9-benzoylanthracene was investigated. It was observed that for each of these compounds the intensity of fluorescence increased remarkably as the external pressure was raised. In each case the enrgy of the fluorescent transiton decreased with increasing pressure leading to a large red shift in the mission spectrum. These data are interpreted to indicate that a change in the energy separating the lowest excited singlet and upper triplet energy levels occur when these compounds are subjected to high pressure.

Mossbauer studies of divalent and trivalent fe57 in coso4 and coso4.7h2o( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

Results are reported of a Mossbauer study of Co57(Fe57) in CoSO4 as a function of temperature at atmospheric pressure and as a function of pressure at room temperature. In addition to the expected divalent Fe57 component, a trivalent component was also observed, the relative intensity of which decreases with increasing temperature or pressure. The isomer shifts of both charge states also decrease with increasing temperature or pressure. The behavior of the large quadrupole splittings observed in each charge state is analyzed using the crystal field approximation. Similar results were also found in a temperature study of CoSO4.7H2O at atmospheric pressure. The relative intensity of the trivalent Fe57 component is considerably greater in the hydrate and also decreases with increasing temperature. (Author)
Mossbauer study of co57 (fe57) in cobaltous oxide at high pressure( Book )

1 edition published in 1965 in English and held by 1 WorldCat member library worldwide

An account is given of a room temperature study of the Mossbauer effect of Co57 (Fe57) in cobaltous oxide up to pressures of about 250 kbar. At atmospheric pressure the Mossbauer spectrum consists of an unsplit line characteristic of divalent Fe57 in a paramagnetic, cubic environment. As pressure is applied to the sample, the spectrum unfolds into a hyperfine pattern characteristic of divalent Fe57 in a magnetic, noncubic environment. This study is consistent with the fact that the Neel temperature of cobaltous oxide (291K at atmospheric pressure) increases with pressure. The pressure dependence of the internal magnetic field, electric field gradient and isomer shift are discussed. (Author)
Isomer shift of fe57 in transition metals under pressure( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

Isomer shifts of Fe57 in several transition metals were measured as a function of pressure up to nearly 300 kbar. The host metals studied were V, Cr, Co, Ni, Nb, Mo, Pd, Ta, W, Pt, and Au. The data are discussed in terms of the volume dependence of (1) the density at the nucleus from 4s-like conduction electrons and (2) the density at the nucleus from 3s core electrons which are shielded by the 3d-like conduction electrons. Results of a previous paper regarding amount of 4s character, n-s, and amount of 3d character, n-d, in the iron impurity atom, are used. The data are shown to be consistent with: (1) n-s decreasing or n-d increasing, or both as one goes through each transition metal series toward more d electrons of the host and (2) n-s decreasing or n-d increasing, or both, as pressure is applied to the host metal. The degree of the effect (2) is shown to be related to the calibration constant of the isomer shift. (Author)
