Book Description
Optical absorption bands at 9.6 and 11.3 eV have been produced in LiF single crystals by x-ray irradiation at room temperature. As the result of an investigation of the thermal bleaching of these absorption bands, they were identified respectively with the alpha- and beta-bands which have not been previously reported in LiF. Significant differences are observed in the variation of these bands relative to the F-band depending on whether thermal or optical bleaching is used. (Author).

Binary Fluorides
Author: Donald T. Hawkins
Publisher: Springer Science & Business Media
ISBN: 1468461478
Category : Science
Languages : en
Pages : 250
Book Description
Coverage For some time, we have contemplated a comprehensive review of the structures and force fields of the binary fluorides. This bibliography of 1498 references marks the first step of that effort. We are pub lishing this material now rather than waiting until the review is complete some two years hence because we believe that the information already accumulated will be of immediate use to a broad spectrum of researchers. Anyone ambitious enough to read through all the articles on binary fluorides will find that the struc tures and force fields of many of these molecules are at present unknown. For example, it has not been clearly established to which point group(s) the lanthanide trifluorides should be assigned. There remain interesting problems relating to the role of Jahn-Teller and pseudo-Jahn-Teller distortions in some of the transition metal fluorides such as VF , MoF , ReF , and ReF , to name only a few. One s s 6 7 also finds fascinating examples of large-amplitude motions, or pseudorotations, as they are often called, in such molecules as XeF 6, I F 7, and PF 5' For those binary fluorides whose equilibrium geometries are precisely known, there still exists the problem of accurately determining the harmonic force field. In a few cases, most notably the Group VA trifluorides, there has been some attempt made at extracting the cubic and quartic contributions to the force field.
