In this work a phenomenological method is developed for the determination of spin configurations of magnetic crystals with a magnetic unit cell un-identical with its chemical unit cell. A finite group, formed of those elements of the space group which are distributed within a magnetic unit cell, is introduced. The expansion of the thermo-dynamic potential in terms of sublattice spin densities is constructed according to the principle that it should be invariant when symmetry operations of the above...

In this work a phenomenological method is developed for the determination of spin configurations of magnetic crystals with a magnetic unit cell un-identical with its chemical unit cell. A finite group, formed of those elements of the space group which are distributed within a magnetic unit cell, is introduced. The expansion of the thermo-dynamic potential in terms of sublattice spin densities is constructed according to the principle that it should be invariant when symmetry operations of the above mentioned group are applied on sublattice spin densities separately. Spin configurations of magnetic crystals are then determined from the minimum condition of thermodynamic potential.

本文发展了一个讨论磁原胞与化学原胞不一致的磁性晶体的自旋位形的宏观方法。引进一个有限羣,其元素乃是分布于一个磁原胞内的空间羣的元素。该羣的对称元素作用于次晶格的自旋密度上,使热力势保持不变。利用这原理可以建立热力势按次晶格自旋密度的展式。由热力势取极小条件决定磁性晶体的自旋位形。 应用这个方法具体地讨论了四类磁性晶体的自旋位形,对每一类情况得到了与中子衍射实验一致的结果。利用本方法在某些情况下,也可以得到螺旋形的自旋位形。

An EHMO calculation has been performed for 2,2,6,6-tetramethyl-4-hydroxypiperidine-l-oxyl(TMHPO). It is shown that the most stable conformation is the chair form with a 12° of “out of plane” angle between the C-N-C plane and the N-O bond, which is consistent with that obtained by X-ray diffraction. The colouration of the nitroxide and the spectroscopic bands of TMHPO in u. v. -visible spectrum may be explained by analyzing the MO levels. The spin density on the nitrogen atom is estimated to be 0.43, from...

It is shown that the most stable conformation is the chair form with a 12° of “out of plane” angle between the C-N-C plane and the N-O bond, which is consistent with that obtained by X-ray diffraction. The colouration of the nitroxide and the spectroscopic bands of TMHPO in u. v. -visible spectrum may be explained by analyzing the MO levels. The spin density on the nitrogen atom is estimated to be 0.43, from which the ESR hyperfine splitting constant is calculated to be 10.8 G,which is in good accordance with the experimental value.

UHF-INDO LCAO SCF MO calculations of cyanoacetio acid free radical (NCCHCOOH)were carried out. The program used is Pople's CNINDO. Data calculated for radical structure of cyanoacetic acid are presented and compared with available experimental results in Tables 1 and 2 and Fig. 2~7 in the Chinese Text.It is confirmed by ESR spectra study and INDO calculation that the free radical trapped in the irradiated single crystal of cyanoacetic acid is in the form of NCCHCOOH. Molecular orbital coefficient, electron density, net atomic charge, spin density and hyperfine coupling constant are calculated for NCCHCOOH radical.Calculations of the isotropic hyperfine coupling constants and the total energy as a function of the NC--C--and--COOH torsion angle θ were carried out and the planar conformation is established in correspondence with a minimum in the total energy of the potential barrier of internal rotation about the carbon-carbon bond calculated to be 7.22 kcal/mol. The isotropic hyperfine coupling constant varies with different torsion angle θ. The best agreement between calculated and observed isotropic constants is found for θ=37°.
