Lorentz triplet

We shall now show that the electron s own magnetic moment, which is bound up with its mechanical moment, supplies the explanation of the anomalous Zeeman effect, i.e. the observed phenomenon that in a (weak) magnetic field a spectral line is split up into a considerable number of lines (fig. 2, Plate VII) while, according to classical theory, and also according to wave mechanics when spin is not taken into account, we can only have the normal Zeeman effect, i.e. the splitting up of every spectral line into a Lorentz triplet. 

These theoretical statements can be tested directly in the case of the normal Zeeman effect. As is well Imown, on transverse observation (at right angles to the magnetic field) we see the normal Lorentz triplet, i.e. a splitting-up into three components. Of these the central one, which corresponds to the transition m -> m and is therefore not displaced, is polarized in the direction of the magnetic field, while the two other components, corresponding to the transitions m i 1 are transversally polarized. In longitudinal observations the undisplaced component disappears and we see only the two displaced components, which, as theory requires, are circularly polarized. 

Now, we interpret the effect of species-solvent molecular asymmetries on the pressure dependence of the kinetic rate constants for reacting systems studied by Roberts et al. (1995) according to the solvation formalism. The system under consideration consists of triplet benzophenone ( BP) as an infinitely dilute reactant, O2 as an infinitely dilute reactive cosolvent, and the infinitely dilute transition state (TS) species all immersed in near aitical CO2 solvent, where all species are described in terms of Lennard-Jones interactions (see Table 8.3) and unlike-pair interactions based on the Lorentz-Berthelot combining rules.
