The performed studies show the linear increase of with increasing pressure. At 10.3GPa, is about 1.36 times higher than at ambient pressure. The obtained trend was explained by a model which considered the effect of pressure on through an induced change of line position, inter-ionic distance, compressibility, and molecular polarizability. A good agreement between the calculated and experimental values for was obtained. | URI: | https://rfos.fon.bg.ac.rs/handle/123456789/1775 | ISSN: | 1042-0150 |
