A Schiff base third-order nonlinear optical material (E)-N′-(4-bromobenzylidene)− 4-fluorobenzohydrazide (BBFBH) was synthesized. It was characterized by victimization chemical analysis techniques like Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (NMR), Ultra-Violet (UV) spectra and Z-scan. The molecular structure of hydrazide derivative C₁₄H₁₀BrFN₂O has been studied with Gaussian 09 using density functional theory. The experimental and theoretical FTIR spectral peaks were analyzed and compared. The absorption in the Ultra-Violet region makes the material to be suitable for optical activity. The static first-order hyperpolarizability (β₀) were calculated and compared with carbamide. The molecule's potential and compatibility in optical limiting applications are revealed by Z-scan investigations.
