Optical Constants of Soot and Their Application to Heat-Flux Calculations
Abstract
Data on the room temperature optical constants of soot are presented for the wavelength regions 0.4–0.8μ and 2.5–10.0/μ. Dispersion formulas are developed for interpolating the data between 0.8 and 2.5μ. The results are used to calculate the spectral absorption coefficient and the total emissivities of soot suspensions. It is shown that the correct values of the optical constants are needed in the use of light-scattering techniques for the measurement of the soot concentration but that uncertainties introduced in flux calculations by use of approximate values of the optical constants are not greater than those introduced by the present uncertainties in the values of the soot concentration.

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.
