Abstract
The bond stretching force constants and the frequencies of the O-H—O bonds in selected crystals where precise experimental deter- minations of the hydrogen positions by diffraction methods are available, were calculated theoretically by making use of the Lippincott-Schroeder potential function to test its applicability for general usage. Experiments in the medium and far infrared regions (100 - 700 cm -^) on these crystals were carried out to locate the hydrogen bond stretching frequencies. These data along with the Raman Spectral data, collected from the literature as well as from our ex- periments, are discussed in relation to the calculated frequencies. These frequencies and force constants were also calculated on this model as a function of O-H—O bond lengths between the limits 2.4 to 3.0A and in intervals of 0.1 A. These results are presented in the form of a table which may be used to approximately determine these quantities as a function of bonded distance. The experimental results show that the potential function used seems to be satisfactory in predicting the hydrogen bond stretching frequencies.
Description
This article appeared in the Faculty Research Bulletin. Begun in 1954, the Faculty Research Edition of the Savannah State College Bulletin was initiated to encourage and publish studies relating to the institution and the fields of special interest of faculty and staff. It contains pure research as well as creative writing. It is primarily a medium for the faculty of SSC, but scholarly papers from other faculties are accepted. Manuscripts that have already been published or accepted for publication in other journals are not included.
