摘要: Abstract Dynamic orbit-lattice interaction parameters for rare-earth ions at any site symmetry group are evaluated under the assumption that static crystal-field determined solely by effects of overlap and covalency. It is shown in two extremes pure σ- or π-bonding there a simple proportionality between values dynamic parameters. Explicit evaluation shows value constant approximately same these extremes. In general no (in strict mathematical sense) parameters, effect this on higher-order terms described. Finally implications analysis interpretation observations pressure EPR spectra briefly noted.
