The pseudo JahnTeller effect is the only source of instability and distortions of highsymmetry configurations of polyatomic systems in nondegenerate states, and it contributes significantly to the instability in degenerate states .The JahnTeller (JT) theorem states that in molecules ions that have a degenerate groundstate, the moleculeion will distort to remove the degeneracy. This is a fancy way of saying that when application of jahn teller effect

The JahnTeller effect (JT effect or JTE) is an important mechanism of spontaneous symmetry breaking in molecular and solidstate systems which has farreaching consequences for different fields, and it is related to a variety of applications in spectroscopy, stereochemistry and crystal chemistry, molecular and solidstate

consequences& illustrations of jahn teller effect 1) JahnTeller distortion in complexes formed by Cu(II) ions: a) Tetragonal structure of Cu(II) complexes: The Cu(II) ion is a d 9 system and expected to show JahnTeller distortion and depart considerably from octahedral geometry. The JahnTeller effect (JT effect or JTE) is an important mechanism of spontaneous symmetry breaking in molecular and solidstate systems which has farreaching consequences for different fields, and it is related to a variety of applications in spectroscopy, stereochemistry and crystal chemistry, molecular and solidstateapplication of jahn teller effect How can the answer be improved?

Free Application of jahn teller effect

The JahnTeller effect is best explained by an example. Consider to that end the square homonuclear molecule in the middle of the top row of Fig. 1. The plane of the figure is the Consider to that end the square homonuclear molecule application of jahn teller effect If one quantum of a JahnTeller active normal vibration in the benzene cation (these are the modes v 69 with e 2g symmetry) is excited, the linear dynamic JahnTeller coupling leads to a splitting into two vibronic states with j12 (E 1g symmetry) and j32 (B 1g B 2g symmetry) vibronic angular momentum.
