Clusters of , = 1 Impurities in , = 0 Solids,ations is finite for . ≲ 20%, as discussed in section 3.4. At sufficiently low concentrations ., it is therefore appropriate to analyze the properties of these solids in terms of . containing small numbers of . = 1 molecules, such as singles, nn pairs, triples with at least two nn separations, etc..Allege 发表于 2025-3-28 19:45:12

In such crystals a . occurs at a transition temperature .. which, in zero-pressure H. and D. at . = 1, is equal to about 3.0 and 4.0 K, respectively, and which decreases with decreasing ..

Rotation Diffusion and Ortho-Para Conversion,xample, this diffusion is responsible for the electrical conductivity of these crystals at high temperatures. In solid H. and D. the diffusion of . = 1 impurities just below the melting temperature has been observed through its effect on the NMR spectra..
