The structural characterization of a new organic compound (3,5-bis(4-chlorophenyl)-4,5-dihydro-1H-pyrazole) was experimentally analyzed using 1 HNMR spectroscopy technique and FT-IR. The HOMO-LUMO analysis and normal bond orbital were examined to study the charge transfer interactions that lead to the properties of nonlinear behavior. The linear optical properties of the new organic compound/film were studied using the Wemble and Didomenico (WD) technique to estimate the refractive index and other optical constants such as oscillation energy and scattering energy. and the mesh isolation constant. The photothermal induced nonlinearity measurements of the compound in a (N-methyl-2-pyrrolidone) solvent were
It was studied by means of an excitation source (a continuous wavelength 473 nm dual laser) in solution state and a conductive polymer film. Z-scan technique was used to measure the nonlinear refractive index)) to obtain the optical response of the prepared materials. The prepared sample showed negative and significant values ​​of saturable reverse absorption (RSA) and also large values ​​of the nonlinear absorption coefficient. The determination of the figure of merit (W) for the nonlinear coefficients indicates that the compound is a promising candidate for applications in the field of nonlinear optics.
