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 po...

We describe a two-laser experiment using optical-optical double resonance fluorescence and Autler– Townes AT splittings to determine the NaK 3 1 →1 X 1 +, 2 A 1 + absolute transition dipole moment functions. Resolved 3 1 →A 1 + and 3 1 →X 1 + fluorescence was recorded with the frequencies of a titanium-sapphire laser L1 and a ring dye laser L2 fixed to excite particular 3 1 =19,J=11, f ←A 1 + ,...

a number of complexes in the series (cu ll'),, where l = [(ch,),c-co-ch-coc( ch,),]-i and l'= 3-(me) c6h,0-, 2,6-(di-me)c6h30-, 4-(oh)c6h?o-, 3- (f) c6h,0-, 4-(br)c6h40-a, nd 3,s-(dl-me)c6h30h- ave been prepared and theu magnetic and optical properties determined. in chloroform, the complexes exhibit two bands in the visible and near uv regions. all complexes show room temperature mag...

The intra-atomic magnetic dipole moment - frequently called ⟨Tz⟩ term - plays an important role in the determination of spin magnetic moments by x-ray absorption spectroscopy for systems with nonspherical spin density distributions. In this work, we present the dipole moment as a sensitive monitor to changes in the electronic structure in the vicinity of a phase transiton. In particular, we stu...

the source parameters and focal depth of the destructive mw 6.5, 31 march. 2006 iran- silakhor earthquake, the two largest foreshocks and a major aftershock are determined using broadband data from a seismic network in iran based on a time-domain linear moment tensor inversion. the earthquakes occurred in the zagros suture zone in western iran. waveform inversion of the selected events estimate...
