Figure 3 shows calculated spectra similar to the fit in Fig. 2a, but for coupling
strengths γ varying from 0 cm-1 to 900 cm-1. It is obvious that the forbidden
transition, denoted by the circle in Fig. 3a, gains intensity through coupling with
the broad, ...

transition involving no change of multiplicity, (3) optically forbidden transition
involving a change of multiplicity. In all three cases, the peak value of has been ...

... an example of such a transition. The e value of the 7r* -» n* band in C2H4 is
approximately 104. An important example of a forbidden transition is the
excitation of a nonbonding 2p oxygen electron in molecules containing the
carbonyl group ...
The forbidden transition is a result of the excitation of one electron from the lone
pair present on the heteroatom to an antibonding n orbital. For example, the n —
> 7t* transition near 300 nm in case of carbonyl compounds with E^ value ...

Nuclear Physics: Principles and Applications
In a forbidden transition, we cannot assume that the matrix element M is
independent of momentum, as we could for an allowed transition. A
consequence of this is that there is an effect on the shape of the B-particle energy
spectrum when L is ...

Forbidden transition: n —> it * transition is an example. In this transition, a
carbonyl n electron of say, a saturated ketone is to be promoted to an orthogonal
(perpendicular) 7T * orbital (n 1 7T *). There would be no orbital overlap for such
90° ...
In an atom a symmetry-forbidden transition can occur only as an electric
quadrupole or a magnetic dipole transition, and this means that the transition
probability is at most 10~6 times the probability of an allowed transition. In a
molecule a ...
