“Explicit assignment: 'bands at 1510 or 1538 (Zn)' but context suggests Pb; snippet says 'sharpCOO@ cm@1(Pb) cm@1' and 'their bands at 1510 or1538 (Zn)' - ambiguous; however, 1538 is associated with Pb carboxylate in literature. Based on snippet: 'sharpCOO@ cm@1(Pb) cm@1' and 'their bands at 1510 or1538 (Zn)', we assign 1538 to Pb carboxylate.”
