In this work, FT-IR, FT-Raman and UV-vis spectra of 1 Phenyl Isatin (1PHISA) were carried out by using HF/6-31 + + G(d,p) and DFT/B3LYP method with 6-31 + + G(d,p),6-311 + + G(d,p) basis sets. The geometric parameters and wavenumbers were obtained and the complete assignments of fundamental vibrations were performed on the basis of potential energy distribution (PED) of the vibrational mode, calculated with scaled quantum mechanics (SQM) method. The hyper conjugative interaction leading to the stability of the molecule and delocalization of charge has been analyzed with natural bond analysis (HBO). HOMO-LUMO energy calculations show the charge transfer within the molecule. Molecular electrostatic potential, hyper polarizability calculations and thermodynamic functions of the compound were also calculated. The biological applications of 1PHISA have been screened out for antimicrobial activity such as antibacterial and antifungal activities. Molecular docking studies were also carried out for different receptors.
