Structural studies on polyethers, [‐(CH2)m‐O‐]n. II. Molecular structure of polyethylene oxide
Abstract
The molecular structure of polyethylene oxide (PEO), (—CH 2 CH 2 O‐)n, was studied by the X‐ray diffraction and infrared absorption spectroscopic methods. The X‐ray diffraction data were observed for the highly oriented PEO samples and were analyzed by use of the method of FOURIER transform of the helix proposed by COCHRAN et al. Fully deuterated PEO was synthesized, and the polarized infrared spectra of PEO and PEO‐d 4 were measured in the 4000–80 cm−1 region. The factor group analysis and the normal coordinate treatments were carried out. From the results of these studies, it was concluded as follows. The PEO molecule in the crystalline state has a helical structure which contains seven chemical units and two turns in the fiber identity period 19.3 Å. The internal rotation angles of this molecule are τ(OCCO) = 64°58′ and τ(CCOC) = 188°15′, and this corresponds to the succession of nearly trans, trans, and gauche conformations.

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.
