چکیده

Steady state fluorescence experiments with mixtures of HD and H2 or D2 have given effective cross sections for energy exchange processes in collisions of electronically excited HD and ground state H2 and D2 molecules in well defined quantum states. The experimental results are compared with first order calculations using the Sharma-Brau theory of energy transfer due to the interaction of transition dipole moments.

A strong enhancement of absorption to the lowest A1 state is observed for vibrationally excited chloromethyl radicals. It is demonstrated that this enhancement is due to a significant increase in both electronic and vibrational Franck–Condon factors.

Microscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives

The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...

– We present results of all-electron electronic structure calculations for the recently discovered d electron heavy fermion compound LiV2O4. The augmented spherical wave calculations are based on density functional theory within the local density approximation. The electronic properties near the Fermi energy originate almost exclusively from V 3d t2g states, which fall into two equally occupied...
