To conceive the nonlinear optical (NLO) phenomena, the third-order susceptibilities (χ(3)) for the title structures have been also derived from the abinitio quantum mechanical procedure (TDHF). According to the computed data on the NLO properties; the cubic hyperpolarizability and susceptibility results of 1-3 are considerably coherent with the measurement values initially produced. © 2019 IEEE.eninfo:eu-repo/semantics/closedAccessSecond hyperpolarizabilityThird-order optical nonlinearityThird-order susceptibilityTime-dependent Hartree-FockConference Object2019-July10.1109/ICTON.2019.88400062-s2.0-85073055178N/A
