We present additional spectroscopic evidence for the formation of low-barrier hydrogen bonds (LBHBs) within vicinal and geminal dicarboxylic acid monoanions. Hydrogen ciscyclohexane 1,2-dicarboxylate, displays low-field 1 H NMR signals in aprotic solvents at 19.3 to 19.7 ppm, depending on the solven
