On the effect of branching and polydispersity on the angular distribution of the light scattered by gaussian coils
Abstract
Analysis shows that the initial curvature of the distribution curve is always smaller for a polydisperse system than for a monodisperse system than for a monodisperse system. From this information and a knowledge of the position of the asymptote, it appears that the curve for a polydisperse case lies below the curve for a monodisperse case. The asymptotic behavior of the angular distribution function is shown to be unmodified by branching. These and other considerations indicate that the precise determination of the whole distribution curve is highly desirable, since it can give useful information about branching or polydispersity provided that only 1 of these 2 effects is present. If both effects are present, the asymptote only permits the determination of the size of unbranched molecules with molecular weight .

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.
