This program is by invitation only.Note that for mixed ethers the “aromatic C-O stretch” as we called it also falls between 1300 and 1200. Take the C-O stretches of a mixed ether, remove the peak because of the saturated ether carbon, and you end up with the C-O stretch of an aromatic ether. The symmetric C-O-C stretch for this molecule falls at 867.
