On the Determination of Transition-Moment Directions
نویسندگان
چکیده
Based on the theory o f photoluminescence polarization, a description o f the determination o f transition-moment directions in luminescent molecules oriented in a stretched polymer film is given. This method is applied to the linear trans-diphenylpolyenes (C2h symmetry): 1,8-diphenyloctatetraene (DPO ), 1,6-diphenylhexatriene (DPH) and 1,4-diphenylbutadiene (DPB). The same transition moment polarized along the long axis o f DPO, DPH and DPB is responsible for ab sorption and fluorescence (ß % 0), when exciting in the long wave absorption band. The results are compared with relevant data obtained from dichroism measurements.

متن کاملEvaluating Response Modification Factors of Concentrically Braced and Special Moment Steel Frames in Duplex Buildings
Response modification factor (R-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. Relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. The present paper tries to evaluate the R-factors of conventional concentric braced frames (CBFs) and special moment frames (MRFs) in ...

In this research. The magnetic phase transition and anisotropic magnetoelastic effects of a polycrystalline sample of Nd14Dy2Fe78B6 were studied by susceptibility and magnetostriction measurements. The composition was prepared by casting method. SEM pictures and XRD analysis showed that it was composed of polycrystalline magnetic phases with the main phase of 2-14-1. Results of ac susceptibil...
متن کاملA new direct yaw moment control with lateral forces effect consideration
Direct Yaw moment Control systems (DYC) can maintain the vehicle in the driver’s desired path by distributing the asymmetric longitudinal forces and the generation of the Control Yaw Moment (CYM). In order to achieve the superior control performance, intelligent usage of lateral forces is also required. The lateral wheel forces have an indirect effect on the CYM and based upon their directio...
