Lande electronic factor

Mixing of LS-states by spin orbit coupling will be stronger with an increasing number of f-electrons. As a consequence, intermediate values of Lande g factor and reduced crystal field matrix elements must be used. 

The number of energy levels found to date, with the aid of the Zeeman effect and the isotope shift data, is 605 even and 586 odd levels for Pu I and 252 even and 746 odd for Pu II. The quantum number J has been determined for all these levels, the Lande g-factor for most of them, and the isotope shift for almost all of the Pu I levels and for half of those of Pu II. Over 31000 lines have been observed of which 52% have been classified as transitions between pairs of the above levels. These represent 23 distinct electron configurations. 

The unpaired d electrons in an isolated transition metal ion or atom possess orbital angular momentum in addition to the spin momentum, and these couple together to give a total angular momentum J. The Zeeman interaction for these ions can be expressed by Eqs. (1) and (2) if S is replaced by J and g by the Lande g factor ... 

The more advanced instrumental methods of analysis, including GC, for the detection and identification of expls are presented (Ref 90) Pyrolysis of expls in tandem with GC/MS was used for the identification of contaminant expls in the environment (Ref 108). Isomer vapor impurities of TNT were characterized by GC-electron capture detector and mass spectrometry (Ref 61). Volatile impurities in TNT and Comp B were analyzed using a GC/MS the GC was equipped with electron capture and flame ionization detectors (Ref 79). The vapors evolved from mines, TNT, acetone, toluene, cyclohexanone and an organosilicon, were analyzed by GC/MS (Ref 78). Red water produced by the sellite purification of crude TNT was analyzed by GC/MS for potentially useful organic compds, 2,4-dinitrotoluene, 3- and 4-sulfonic acids (Ref 124). Various reports were surveyed to determine which methods, including GC/MS, are potential candidates for detection of traces of TNT vapors emitted from land mines factors influencing transportability of TNT vapors thru soil to soil/air interface are dis-... 

Starting from a multipole expansion of intramolecular Coulomb interactions, we present an efficient configuration interaction calculation for the electron terms = 2,3, 4, and the hole terms (hf)", n = 2-5. We have studied magnetic moments for the electron and hole terms. The coupling of spin and orbital momenta differs from the Lande g-factor scheme of atoms. The magnetic moments do not depend on the orientation of the molecule with respect to an external magnetic field. 

The factor g in Eqs. 8.14 and 8.15 is a dimensionless quantity called the electron, or Lande g factor (or spectroscopic sphtting factor) and, for the case of a. free electron, it equals precisely 2.0023193. However, it will be seen later that it can have other values when the electron is in condensed matter. 

The parameter g, the Lande g factor, has a value close to 2 for electrons in free space and in practice for most organic radicals. 

The suffix 1 was added to emphasize that this expression is only valid for one electron. Combining terms and introducing a factor g, known as the Lande splitting factor, one arrives at... 

The constant of proportionality g equals 2.0023 for a free electron and is called the spectroscopic splitting factor, or just the g factor. It is equivalent to the Lande g factor of atomic spectroscopy.
