Sulfur Stable Isotope Discrimination in Rice: A Sulfur Isotope Mass Balance Study [PDF]

open access: yesFrontiers in Plant Science, 2022
The use of sulfur (S) stable isotopes to study S metabolism in plants is still limited by the relatively small number of studies. It is generally accepted that less S stable isotope discrimination occurs during sulfate (SO42–) uptake.

Sulfur Isotope Effects of Dissimilatory Sulfite Reductase [PDF]

open access: yesFrontiers in Microbiology, 2015
The precise interpretation of environmental sulfur isotope records requires a quantitative understanding of the biochemical controls on sulfur isotope fractionation by the principle isotope-fractionating process within the S cycle, microbial sulfate ...

Five-S-isotope evidence of two distinct mass-independent sulfur isotope effects and implications for the modern and Archean atmospheres [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
The signature of mass-independent fractionation of quadruple sulfur stable isotopes (S-MIF) in Archean rocks, ice cores, and Martian meteorites provides a unique probe of the oxygen and sulfur cycles in the terrestrial and Martian paleoatmospheres.

Wet feet: developing sulfur isotope provenance methods to identify wetland inhabitants [PDF]

open access: yesRoyal Society Open Science, 2023
The stable isotopes of sulfur provide a distinctive signature for marine proximity and interaction. Exploring coastal proximity has been the principal application of sulfur isotopes in archaeology and palaeoecology, but this deals only with high (greater

Molecular insights into the dynamic relationship between respiration rate and sulfur isotope effect [PDF]

open access: yesApplied and Environmental Microbiology
Microbial sulfate reduction and its resulting sulfur isotope effects are crucial for understanding the past and present sulfur cycle. Microbial S-isotope effects have often been explained by their inverse correlation with the cell-specific sulfur ...

Multiple-sulfur isotope effects during photolysis of carbonyl sulfide [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
Laboratory experiments were carried out to determine sulfur isotope effects during ultraviolet photolysis of carbonyl sulfide (OCS) to carbon monoxide (CO) and elemental sulfur (S<sup>0</sup>).

Calculations of Thermodynamic Sulfur Isotope Effect [PDF]

open access: yesJournal of Nuclear Science and Technology, 1985
The isotopic reduced partition function ratios (RPFR), (s/s')f, for the 34S/32S isotopic pair were calculated for 24 sulfur compounds between 10 and 2,000K. Their magnitudes were in the following sequences; at low enough temperatures at which In(s/s')f depends only on the isotopic difference in frequency-sum, SF6>SO2F2>SF5Cl>SF5Br>SO4 2->SO2Cl2>SO3 ...

Research Progress of Sulfur Isotope Analytical Techniques

open access: yesJournal of Isotopes, 2023
Sulfur is widely distributed in nature, with various valence states such as -2, -1, 0, +4, +6, etc. The common occurrence forms include sulfate, sulfite, thiosulfate, elemental sulfur.
