چکیده

Tris complexes of Ln3+ ions (Ln = La, Ce, Pr) with triphenyl-substituted cyclopentadienyl ligands were studied by optical spectroscopy. Emission both 5d - 4f and transitions was observed for Pr3+ complex. It found that the strength crystal field formed in tris is comparable to case sulfides, as a result, red luminescence Ce3+ compound. The quantum yield photoluminescence 20% latter.

A Crossed Beam and ab Initio Investigation on the Formation of Boronyldiacetylene (HCCCC<sup>11</sup>BO; <italic>X</italic><sup>1</sup><sup>+</sup>) via the Reaction of the Boron Monoxide Radical (<sup>11</sup>BO; <italic>X</italic><sup>2</sup><sup>+</sup>) with Diacetylene (C<sub>4</sub>H<sub>2</sub>; <italic>X</italic><sup>1</sup><sub>g</sub><sup>+</sup>)

The reaction dynamics of the boron monoxide radical (BO; XΣ) with diacetylene (C4H2; XΣg) were investigated at a nominal collision energy of 17.5 kJ mol−1 employing the crossed molecular beam technique and supported by ab initio and statistical (RRKM) calculations. The reaction is governed by indirect (complex forming) scattering dynamics with the boron monoxide radical adding with its boron at...
