Experimental and Theoretical EPR Study of JahnTeller
The trigonally symmetric Mo(III) coordination compounds [HIPTN3N]MoL (L = N2, CO, NH3; [HIPTN3N]Mo = [(3,5-(2,4,6-i-Pr3C6H2)2C6H3NCH2CH2)3N]Mo) are low-spin d3, S = 1/2) species that exhibit a doubly-degenerate 2E ground state susceptible to a Jahn-Teller (JT) distortion. The EPR spectra of all three complexes and their temperature and solvent dependences are interpreted within a formal ‘2-orbi...
متن کاملDumbbell rattling in thermoelectric zinc antimony.
Inelastic neutron scattering measurements on thermoelectric Zn4Sb3 reveal a dominant soft local phonon mode at 5.3(1) meV. The form factor of this local mode is characteristic for dumbbells vibrating preferably along the dumbbell axis and can be related to a vibration of Sb dimers along the c axis. The Lorentzian width of the mode corresponds to short phonon lifetimes of 0.39(2) ps and yields a...
متن کاملRattling the cage and opening the door.
I share with Poulin-Dubois and with Sabbagh, Koenig and Kuhlmeier the conviction that more research is needed on the mechanisms supporting selective social learning in infants and children. However, my plea is more specific: for research that tests domain-specific hypotheses about mechanism against domain-general hypotheses derived from other fields of cognitive science. Many, but not all, of t...
متن کاملRattling and freezing in a 1-D transport model
We consider a heat conduction model introduced in [2]. This is an open system in which particles exchange momentum with a row of (fixed) scatterers. We assume simplified bath conditions throughout, and give a qualitative description of the dynamics extrapolating from the case of a single particle for which we have a fairly clear understanding. The main phenomenon discussed is freezing, or the s...
متن کاملRattling ‘‘guest’’ impurities in Si and Ge clathrate semiconductors
In addition to their ground state, diamond structure, Si, Ge and Sn can form crystalline solids called clathrates. As in the diamond structure, in the clathrates, the Group IV atoms are tetrahedrally coordinated and sp covalently bonded to their neighbors. However, the clathrates contain pentagonal atomic rings and have open-framework lattices containing 20-, 24and 28-atom ‘‘cages’’. There are ...
