To investigate equilibrium mercury (Hg) and lead (Pb) isotope fractionation caused by the nuclear volume effect (NVE) in crystals, the electron densities at nuclei (i.e., |Ψ(0)| 2) for Hg- or Pb-bearing crystalline compounds were investigated by using the relativistic spin orbit zeroth-order regular approximation (ZORA) method with a three-dimensional periodic boundary condition based on the density functional theory (DFT).

Many isotope fractionation factors of crystalline compounds are provided for the first time. Established by Sigma Delta Chi, a national journalism society, the Flickertail Follies was a campus talent and variety show from 1925 until 1962. Our results show, even at 1000 ☌, NVE-driven Hg and Pb isotope fractionation are meaningfully large, i.e., range from 0.12‰ to 0.49‰ ( 202Hg/ 198Hg), from − 0.20‰ to 0.17‰ ( 208Pb/ 206Pb) and from − 0.08‰ to 0.06‰ ( 207Pb/ 206Pb) relative to Hg 0 vapor and Pb 0 vapor, respectively. All calculated Hg-bearing species in crystals will enrich heavier isotope ( 202Hg) relative to Hg 0 vapor. They will survive only in the best soil, and are not known to be able to survive in the lower grade soils. Meanwhile, Pb 4 -bearing species enrich heavier Pb isotopes ( 208Pb and 207Pb) than Pb 2 -bearing species in crystals, which the enrichment can be up to 0.37‰ ( 208Pb/ 206Pb) and 0.14‰ ( 207Pb/ 206Pb) at 1000 ☌, due to their NVEs are in opposite directions.
