violates this last selection rule, and intercombination transitions, whose probabilities are greater the greater the atomic number of the element, appear. Special selection rules for electronic, vibrational, and rotational molecular spectra exist for molecules, rules that are determined by the symmetry ...
transition in Helium, and I have come across a question. It is clear that triplet-singlet transition are not allowed, i.e. ΔS=0. But in my book (Foot's Atomic Physics) it says that Δl = ±1. This is what I don't understand. The selection rule Δl = ±1 we derived for.....

The electron-phonon (el-ph) and phonon-phonon interactions play crucial roles in determining the electronic and thermal transport properties of materials. Using the group theory and ab-initio calculations, we have derived the full-landscape selection rul
1c. This symmetry breaking plays a key role in their response to electric fields, even when the simple selection rule, summarized in Fig. 1a, b, suggests no response. Results DW-localized phonons We use the Ginzburg–Landau–Devonshire (GLD) model for DWs in BFO to capture the energetics ...
Key Use(s): A broad range of applications that spans from bumpers to bellows, vibrational dampers, couplers, and grommets. Also used throughout the automotive, major and small appliances, and aerospace industries. Features: In virtually all cases, the substitution of these materials for ...

This breaking of the symmetric–antisymmetric selection rule gives access to the antisymetric stretching levels of the ground electronic stateX̃ Σ+ g from the 15 V excitation. We also show that, below 12 000 cm−1, the vibrational couplings of CS2 can be described by a model of 2...
All but the reference level of theory calculations were performed in the Gaussian16 [70] quantum chemistry package, with a very tight geometry optimization cut-off and ultrafine integration grid, as is recommended for all DFT calculations. A vibrational analysis was conducted at each stage of the...
