Abstract

Light on chirality: To predict the enantiomeric enrichment that can be induced into racemic organic molecules with the help of circularly polarized light, the anisotropy factor g is essential. Anisotropy spectra g=f(λ) recorded for proteinaceous amino acids provide crucial information on the transfer of chirality from light to matter.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Asymmetric photolysis of racemates can induce enantiomeric excess approximated by eqn (2) when anisotropies are close to zero.

    “In the common case of two competitive pseudo-first order photolytic reactions with unequal rate constants, k S and k R , for the (S) and (R) enantiomers, respectively, and if the anisotropies are close to zero, the enantiomeric excess induced by asymmetric photolysis can be approximated as eqn (2): 188”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
