    • Note: These are quadrupole moment of the f-electron charge cloud, where prolate electron density signifies that the electron charge cloud is axially elongated, the preferred geometry is equatorially coordinated, and, for oblate electron density, the electron charge cloud is equatorially expanded; the crystal field should lie above and below the XY plane.

    • Note: In lanthanide chemistry, the splitting of the mJ states due to the weak crystal field is often referred to as the Stark splitting, and the states themselves are referred to as Stark sublevels.

    • note
    • Note: (a) Orbach process is a type of spin-lattice relaxation and depends on the splitting pattern of the three involved states. The rate for this process vanishes for T → 0 K exponentially..

    • (b) Raman process is a type of two-phonon direct spin-lattice relaxation mechanism, where the spin system is under non-adiabatic conditions. Such analysis permits us to make a detailed study of this process, including the case of multilevel ground states (S-electron ions with hyperfine interaction), as well as the case of the sharp resonant modes associated with the paramagnetic impurities..

    • note
    • Note: It is important to note here that Raman and Orbach processes cannot be directly determined by these matrix elements. These matrix elements can be useful as the indicator toward these processes.

    • note
    • Note: (a) studied models are fictitious and not optimized structures, thus the Er-O-H angles are expected to be non-linear. Other possible linear arrangements are Er-C-N moiety which are also reported in the literature..
