The ν(CO) and νop(CO)2 modes for 4-x benzoic acids in CHCl3 and/or CCl4 solutions decrease in frequency as the σp values for the 4-x atoms or groups decrease in value while the ν(OH) mode increases in frequency. Different complexes are formed between the CO2H and (CO2H)2 groups as the mole% CHCl3/CCl4 changes from 0 to 100.
