Answer to: Draw the Lewis structure for HCN. Determine the number of electron groups, the electron geometry, and the molecular shape. Is it polar...
From left to right: a beam of negative astatine ions (blue circles) is guided into GANDALPH49,50, where the ion beam is overlapped with a frequency tuneable laser beam (red line) in the interaction region in either co- or counter-propagating geometry. By absorbing a photon (Inset 1), ...
The local excitation triplet state (3LE) and charge-transfer triplet state (3CT) configurations and highest occupied and lowest unoccupied molecular orbitals (HOMO and LUMO) of (a) DTCz-DPS-1, (b) DTCz-DPS-2, and (c) DTCz-DPS-3. The molecular geometry, relative Gibbs free energy, and...

To maximize the efficiency of ...
This approach requires generating initial structure models either at random or based on the known molecular connectivity for organics or known polyhedral geometry for inorganic compounds [55,56,57]. In global optimization methods, the positions of individual atoms as well as the global shift and ...
Emission properties were probed in diode arrangements with parallel-plate field geometry; the field was produced in gaps of d = 0.6 mm width between each specimen and an opposite molybdenum cylindrical flat-top anode. The spacers used to set the gaps’ width were removed before evacuation of ...
