text: Similarly for rare-earth ions where covalency is very small, the distortions associated to the JTE are usually very weak.
text: Dynamic Jahn-Teller distortion: In some molecules, the distortion is not seen either due to random movements of bonds which does not allow the measurement within a time frame or else the distortion is so weak as to be negligible.
