Abstract
Abstract
Conformers of 3-halogenobenzaldehydes (3HB, halogen atom: F [3FB], Cl [3CB] and Br [3BB]) in the gas phase and solutions were studied using density functional theory (DFT) and time dependent density functional theory (TDDFT), B3LYP functional and MP2 method with 6–311+G(3df,p) and aug-cc-pVDZ basis sets. The present study aims to investigate the halogen and medium effects on the conformational stability, structural parameter, dipole moment, carbonyl stretching frequency, frontier molecular orbitals, band gap, absorption band and density of states. Carbonyl stretching frequencies were evaluated with some solvent models. All results will be useful for further analysis of halogen-substituted benzaldehydes.
