The one-photon absorption (OPA) and two-photon absorption (TPA) characterizations have been determined by configuration interaction (CI) and time-dependent Hartree-Fock (TDHF) methods, respectively. The averaged (isotropic) second hyperpolarizability (<gamma >) allows the determination of the third-order optical response. The ab-initio calculation on <gamma > with non-zero value reveals that the title dye has relatively good third-order NLO properties. The calculated results of 1 on OPA wavelength, TPA cross-section (delta(omega)) and third-order susceptibility are in reasonable agreement with its experimental data.eninfo:eu-repo/semantics/closedAccessZ-scannonlinear absorption parameterthird-order susceptibilitysecond hyperpolarizabilityUV-Vistwo-photon absorptionConference ObjectN/AWOS:000346516400381N/A
