Ether c-o stretch
Web1280-1300 C-O stretch (ether) 1100-1150 C-N stretch (amide) Based on the IR spectrum, the major peaks observed at 1680 cm-1 and 1280-1300 cm-1 are consistent with the presence of an amide and an ether functional group, respectively. The peak observed at 1100-1150 cm-1 is consistent with a C-N stretch in an amide group. WebThe carbonyl stretch C=O of a carboxylic acid appears as an intense band from 1760-1690 cm-1. The exact position of this broad band depends on whether the carboxylic acid is saturated or unsaturated, dimerized, or has internal hydrogen bonding. O–H stretch from …

But because when the next tier of weapons after +25 akkan drops, the gap will become smaller again and they'll have to release esther 9 to widen the gap again. Then whales will be obliged to spend thousnands of $$$ again.
