Oxygen isotope fractionation factors involving cassiterite (SnO2): I. calculation of reduced partition function ratios from heat capacity and X-ray resonant studies

“…The significant merit of the new technique is that the SOD is obtained independently of chemical isomer shifts. PHOENIX investigations of SnO 2 crystal were conducted by Hu et al (1999). The VDOS of the Sn sublattice of SnO 2 obtained by Hu et al (1999) is presented in Figure 4, where the Debye spectrum corresponding to M ϭ 430 K is also shown for comparison.…”

The VDOS of the Sn sublattice of SnO 2 obtained by Hu et al (1999) is presented in Figure 4, where the Debye spectrum corresponding to M ϭ 430 K is also shown for comparison. One can see the significant difference between the two spectra.…”

“…We computed the characteristic temperatures 2i by Eqn. 9, using the VDOS from Hu et al (1999): 2 ϭ 350.9 Ϯ 4.5; 4 ϭ 451.3 Ϯ 11.7; 2 ϭ 546.1 Ϯ 22.4.…”

“…Since our Mössbauer experiments do not contradict accurate synchrotron radiation results, we use the VDOS obtained by Hu et al (1999) in our further calculations of ␤ 18 O-factors of cassiterite,…”

“…In the second paper of the series (Hu et al, 2005), we evaluate the oxygen isotope fractionation factor by the laboratory isotope-exchange method and compare the results obtained by the two methods.…”
