The rise of Virtual Reality (VR) in educational contexts has highlighted the need to design Learning Applications (VRLAs) that prioritize inclusivity, accommodating a spectrum learner needs. Despite surging interest, there is noticeable gap research delves into specifics creating VRLAs are rooted inclusive theory. This sought extract insights and recommendations for development tailored diverse student populations. intention was scrutinize focused on elements VRLAs, leading establishment...
The 2H solid state NMR spectra and T1 relaxation data of a transition metal η2-dideuterium complex, namely trans-[Ru(D2)Cl(PPh2CH2CH2PPh2)2]PF6, have been measured in the temperature regime from 5.4 to 320 K. In Ru–D2 sample, coherent incoherent exchange processes on time scale quadrupolar interaction found, leading at low temperatures tunnel splitting spectrum. With increasing slight increase is observed, conjunction with strong process, which finally, above 20 K, destroys determines...
A selectively η2-D2 labeled isotopomer of the complex W(PCy3)2 (CO)3) (η2-D2) has been synthesized and 2H NMR spectra spin lattice relaxation rates this have measured in temperature regime 50 K to 300 K. The analyzed employing a model combination homonuclear dipolar D−D interaction deuterium quadrupolar distance 0.89 ± 0.1 Å. line width exhibits weak dependence at temperatures above 150 This is interpreted as slight decrease coupling with increasing temperature, which an indication change...
In this paper a simple phenomenological description of the effects coherent quantum and incoherent mutual exchange two deuteron nuclei in solid state transition metal complexes on their 2H NMR spectra is given. This based quantum-mechanical density matrix formalism developed by Alexander Binsch. Only nuclear spin system treated mechanically. The interaction included Hamiltonian, with surrounding bath processes are as rate described constants. corresponds formally to 180° rotations or jumps...
Das Spannungsfeld zwischen Personalisiertem Lernen auf der einen und Kooperativem anderen Seite kann anhand theoretischer empirischer Forschungsarbeiten sowohl für inklusive als auch digitale Lehr-Lern-Umgebungen konstitutiv gelten. Dieser Beitrag basiert daher These, dass die Zusammenführung inklusionsorientierter digitaler Prozesse Personalisierung bzw. Individualisierung immer mit interaktionistischen kooperativen Lehr-Lern-Prozessen zu verbinden auszugleichen sind. Auf Basis einer...
The title compound N-aminopyrazole (AMPZ) has been studied both theoretically and experimentally using abinitio methods, low-temperature X-ray crystallography, differential scanning calorimetry, IR spectroscopy, liquid state 1H NMR, broadband solid 2H NMR high resolution 15N focussing on the structure dynamics of amino group characteristics hydrogen bond (HB) association. complete rotation–inversion surface AMPZ and, for comparison, also aniline monomer were calculated at B3LYP/6-31G* level....
