UV Photolysis of N2O Isotopomers: Isotopic Fractionations and Product Rotational Quantum State Distributions
Time-dependent wavepacket Isotopic fractionation Product rotational distri-bution
2012/4/5
The time-dependent quantum wave packet method is used to study the dynamics of the pho-todissociation processes for the isotopomers 14N14N16O, 14N15N16O, 15N15N16O, 15N15N16O, 14N14N17O, and 14N14N18O...
Isotopic Effects on Stereodynamics for Ca+HCl, Ca+DCl, and Ca+TCl Reactions
Isotopic effect Stereodynamics Quasi-classical trajectory Vector correlation
2012/4/5
The vector correlations in Ca+HCl, Ca+DCl, and Ca+TCl reactions have been investigated by means of the quasi-classical trajectory calculations on PES constructed by means of multireference configurati...
Identifying organic matter provenance in sediments using isotopic ratios in an urban river
riverine sediment isotopic ratios effluent C3 plants sources
2017/8/9
To provide a better understanding of potential hazard of effluent detritus, both at the present and in the future, the dispersal and accumulation of sewage-derived materials in the receiving river sho...
Isotopic evidence of boron in precipitation originating from coal burning in Asian continent
boron isotopes coal burning trace elements Asian continent long-range transport
2017/8/9
The boron concentration and isotopic composition (δ11B) of precipitation collected from December 2002 to March 2006 at three sites on the Japan Sea coast were measured. Those sites have been considera...
Hydrogen isotopic fractionation in lipid biosynthesis by H2 -consuming Desulfobacterium autotrophicum
lipid biosynthesis Hydrogen isotopic fractionation
2014/4/8
We report hydrogen isotopic fractionations between water and fatty acids of the sulfate-reducing bacterium Desulfobacterium autotrophicum. Pure cultures were grown in waters with deuterium (D) content...
