Effect of molecular rotation on enantioseparation [PDF]

open access: yesThe Journal of Chemical Physics, 2012
Recently, several laser schemes have been proposed to separate racemic mixtures of enantiomers by splitting a molecular beam into subbeams consisting of molecules of definite chirality [Y. Li, C. Bruder, and C. P. Sun, Phys. Rev. Lett. 99, 130403 (2007);

Possible Enantioseparation of Racemic Ribose on Chiral Surface Formed by Adsorption of Nucleobases [PDF]

open access: yesLife
The paper proposes a putative prebiotic scenario leading to homochirality in the RNA world. In this scenario, racemic ribose, the only chiral moiety in RNA, was enantioseparated (in its pyranose form) on a chiral surface formed by the adsorption of ...
