Ethylene Oxide | C2H4O | CID 6354 - PubChem
Ethylene oxide is a man-made chemical that is used primarily to make ethylene glycol (a chemical used to make antifreeze and polyester). A small amount (less than 1%) is used to control insects in some stored agricultural products and a very small amount is used in hospitals to sterilize medical equipment and supplies.

6.7: ¹H NMR Spectra and Interpretation (Part II)
2021年12月16日 · In the 1 H NMR spectra that we have seen so far, each set of protons generates a single NMR signal. This is not that common for 1 HNMR actually. In fact, the 1 H NMR spectra of most organic molecules contain signals that are ‘split’ into two or more peaks that is called splitting (or coupling ).

2003年3月19日 · The reorientational and translational dynamics of the polymer, anion and cation species in polymer electrolyte systems consisting of a cross-linked poly(ethylene oxide−propylene oxide) random copolymer (poly(EO−PO)) doped with LiN(SO 2 CF 3) 2 at two different cross-linking densities were studied using multinuclear NMR relaxation and pulsed ...
13C NMR characterization of ethylene oxide/propylene oxide …
Analytical studies are essential if ethylene oxide (EO)/propylene oxide (PO) adducts are to be comprehensively characterized. Because hardly any detailed information on their structure has previously been available, studies were carried out to assess the value of the information obtained by 13 C NMR spectroscopy.
