Mass-resolved electronic circular dichroism ion spectroscopy

Open access

Abstract

DNA circular dichroism in gas phase: Circular dichroism spectroscopy is widely used to distinguish between nonidentical mirror-image molecules. The technique relies on differential absorption of left versus right circularly polarized light and therefore tends to require solution-phase samples for adequate sensitivity. Daly et al. now report gas-phase circular dichroism spectra of DNA oligonucleotides based on detection of photodetached electrons rather than transmitted light (see the Perspective by Barran). The salient spectral features matched those in solution. Pairing the technique with mass spectrometry enables prior mass selection of particular molecules for analysis.

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?

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.
