The degenerate rearrangement on Jahn-Teller distorted metal complexes is a promising reaction for the observation of significant heavy atom quantum mechanical tunnelling. Herein, a family of Cu(ii)-N complexes are theoretically proven to exhibit rapid dynamical Jahn-Teller tunneling even close to the absolute zero. The manifestation of our predictions apparently appeared in solid state EPR experimental measurements on [Cu(en)]SO more than 40 years ago, without the authors realizing that it was a quantum outcome.
对于 Jahn-Teller 畸变金属配合物，简并重排是观察显著重原子量子力学隧穿的一个有前景的反应。在此，一族 Cu(ii)-N 配合物在理论上被证明即使接近绝对零度也会表现出快速的动态 Jahn-Teller 隧穿。我们预测的表现早在 40 多年前对 [Cu(en)]SO 的固态 EPR 实验测量中就明显出现了，而作者并未意识到这是一个量子结果。
