The molecular geometry of the complex of gallium trichloride with ammonia, Cl 3Ga.NH 3, has been studied by electron diffraction. The most important internuclear distances in terms of r a parameters are as follows: r(Ga-Cl) = 2.142±0.005, r(Ga-N) = 2.057±0.011, r(ClCl) = 3.642±...

Electron spin resonance spectroscopy Polycrystalline assembly of 10–15 rod-like MAMn:PbI3samples with typical 1 × 0.1 × 0.1 mm are sealed in a quartz capillary. ESR at 9.4 GHz microwave frequency was performed on a Bruker X-band spectrometer. A conventional field modulation technique ...
An electron storage ring was operated with energy of 1.5 GeV and a current of 360 mA. A Si(1 1 1) DCM was used for providing highly monochromatized photon beams with energies of 0.9 to 9 keV and resolving power (E/ΔE) of up to 7000. Data were collected in fluorescence or ...
The formation of σ-hole complexes is expected to result in the transfer of electron density into the σ*(Z–F1) antibonding orbital. This shift will lengthen this bond, as already noted above, and will weaken the bond and thereby shift the stretching frequency to the red. A comparison of...

The concentration, structure and coordination environment of isolated Cu2+ ions were investigated using electron paramagnetic resonance spectroscopy (EPR). The EPR spectra were recorded at room temperature with a Bruker EMXmicro X-band spectrometer (Rheinstetten, Germany). The modulation amplitude and ...
(4) The formation of a tetrel bond was accompanied by a charge transfer from the lone pair on the N atom of NH3 to 6-OTX3-fulvene, thus, it resulted in an increase in the electron density on the fulvene ring and its aromaticity. Author Contributions: Conceptualization, Q.-Z.L. and ...
The intercalated H2O increases the electron density for the (200) plane, where the MA cation is located, which results in higher intensities in the diffraction pattern. These findings are in common with a work from Christians et al., who studied the influence of humidity on MAPBI3 materials ...
