selection rulesenergy spectrumThe energy spectrum and bound-bound interband transitions in semiconductor quantum dots are analysed within the effective mass approach. Interband bound-bound transition intensities are calculated and it is shown that the conventional l=const selection rule is slightly lifted...
Selection Rules for Transitions Transitions between states of the same parity are forbidden. Laporte Selection Rule Transitions between states of different spin multiplicities are forbidden. 4A2 4T1 and 4A2 2A2 Discuss how the rules are relaxed on the expected absorption intensities. Tanabe-...
Most fabrication steps used standard processes used in flexible electronics manufacturing, minimizing the need for custom equipment and materials, enabling an easy transition from prototyping to manufacturing. The concept and demonstrations of helical e-strip stretchability are presented in Fig. 1. Figure...
a photocurrent. The visible pulse chosen here is off-resonant with this electronic transition such that the visible pulse alone does not electronically excite the sample; only the combination of vibrational and electronic transitions populates the electronic excited state and produces photocurrent. More...
The I (1/2) u →I (3/2) g transition, which occurs in the near infrared, is very weak in accordance with propensity rules based on changes in Ω. The I (1/2) u →I (1/2) g transition occurs between 700–800 nm and grows dramatically in intensity from Ar+ 2 to Xe+ 2...

The first of these effects requires that the given transition is allowed by both single-quantum (electric dipole, E1) and two-quantum (E12) selection rules. In fact, for polar molecules of every symmetry type, all of their conventional (i.e., E1-allowed) electronic transitions are also E12...
Hence, intra- and inter-band dimer coherences can be found in the time–frequency maps in a small range of short 𝑇1T1 values and in a range of 𝜔3ω3 values which is defined by the transition energies from the FS states involved in the coherences to the GS. The fact that the ...
