Selection rules for vibronic d → d transitions of impurity ions in cubic KMgF 3From the effect of stress on the polarization of the optical emission spectra of V 2+ and Ni 2+ in KMgF 3 we determine the selection rules governing the vibronic transitions. Most of the one-phonon vibronic ...

11 It is then possible to translate them into selection rules for transitions between all known 3-manifolds =-=[4]-=-. 11 Their result is the following: Let Σ = Σi ∪Σf be the spacelike boundary of the Lorentz manifold M, then dim ` H 0 (Σ,Z2) ´ +dim ` H 1 (Σ,Z...
The revealed selection rules indicate that the excitations responsible for the coupling of light to spins are d-d electron transitions in octahedral and tetrahedral Co-sublattices, respectively.Similar content being viewed by others Ultrafast opto-magnetic effects in the extreme ultraviolet spectral range...

Optical selection rules fundamentally determine the optical transitions between energy states in a variety of physical systems, from hydrogen atoms to bulk crystals such as gallium arsenide. These rules are important for optoelectronic applications such as lasers, energy-dispersive X-ray spectroscopy, and...

Rapid evolution of reproductive traits, due to both relaxed selection and directional selection under the new status of predominant selfing, lays the genetic groundwork for reproductive isolation. Consequently, shifts in sexual selection pressures coupled to transitions to selfing provide a powerful ...
