Terahertz time-domain spectroscopy of water vapor

van Exter, Martin, Fattinger, Ch., Grischkowsky, D.·1989·Optics Letters

Abstract

We describe the application of a new high-brightness, terahertz-beam system to time-domain spectroscopy. By analyzing the propagation of terahertz electromagnetic pulses through water vapor, we have made what we believe are the most accurate measurements to date of the absorption cross sections of the water molecule for the nine strongest lines in the frequency range from 0.2 to 1.45 THz.

Statistics

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

Claims the paper makes

This paper’s full text isn’t openly available, 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?

  • By knowing the refractive indices of the layers under test, the thickness of each layer can be derived from extended analysis of the reflected or transmitted terahertz signal even for sub-wavelength thicknesses.

    “By knowing the refractive indices of the layers under test, the thickness of each layer can be derived from extended analysis of the reflected (or transmitted) terahertz signal even for sub-wavelength thicknesses [2-4].”

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.
