Modified Florence approach

The approach of Bertini et al. 119) and Kruk et al. 96) was implemented in the software package developed in Florence 107) and is called the modified Florence method . The corresponding program is available in public domain (www.postgenomicnmr.net). The predictions of the ZFS rhombicity-dependence (for S = 1) of the modified Florence approach are compared with the general theory, with the original Florence method 107) and with the SBM approach in Fig. 10, taken from the work of Bertini et al. 119).

Chemistry is a weird science where the canon rules of simplicity and complexity are viewed as intrinsic coexisting denominators. If this proposition is shared, the prerequisites mentioned above do not fulfil the chemical world. The development of chemical research in its own different fields requires that the usual philosophical approaches must be modified and improved. This as an example is the case of the characterization of molecular systems in mesoscopic scale. A limited number of findings, which has been obtained in the Florence Laboratory for the study of magnetic materials (LAMM), will be discussed here with the aim of supporting this statement.
