Vibrational Studies of Monomer, Dimer and Trimer Structural of 4-Carboxy Phenylboronic acid

4-Carboxy Phenylboronic acid (4-cpba) was investigated theoretically and experimentally by spectroscopic methods such as FT-IR Raman. The molecular structure parameters were determined computational methods. dimer1, dimer2 trimer structures for intermolecular hydrogen bonding. Moreover, minimum conformational energy search carried out potantial surface (PES). Potential distribution analysis of normal modes performed to identify characteristic frequencies. findings this research work should be useful experimentalists in their quests functionalised 4-cpba derivatives.
