每個(gè)Mn4單元中的四個(gè)Mn(III)離子配位環(huán)境均不同，每?jī)蓚�(gè)Mn(III)離子之間的連接方式也不盡相同，Mn(III)離子之間的磁耦合關(guān)系非常復(fù)雜，在此為了定性地考察錳離子之間的磁相互作用的強(qiáng)度，將四個(gè)錳離子之間的耦合關(guān)系簡(jiǎn)化，使用一個(gè)耦合常數(shù)J來考察。另外，為了減少計(jì)算中的參數(shù)、簡(jiǎn)化模型，分子間的通常較弱的磁相互作用貢獻(xiàn)在此也不予考慮。根據(jù)正四面體排列的MnIII4體系（圖解1）的自旋哈密頓算符Ĥ = -2J(Ŝ1Ŝ2+Ŝ1Ŝ4+ Ŝ2Ŝ3+ Ŝ3Ŝ4)，可導(dǎo)出該體系的磁化率表達(dá)式（公式1） The crystal structure of 1 shows that the coordination environments of four Mn(III) ions in every Mn4 units are different from each other and the bridging modes of every two Mn(III) ions are not completely the same indicate that the magnetic coupling relations between Mn(III) ions are extraordinary complicated. To qualitatively evaluate the magnitude of the magnetic interaction in manganese ions, we tried to simplify the coupling relation between the four Mn(III) ions with one coupling constant J. In general, the weaker magnetic interaction are not considered in order to reduce the calculation parameters and simplify the model. The layer can be schematically illustrated in Scheme 1. On the basis of the regular tetrahedron arrangement of MnIII4 model, the magnetic susceptibilities can be fitted accordingly by the following expression given in Equation (1) derived from the spin Hamiltonian Ĥ = -2J(Ŝ1Ŝ2+Ŝ1Ŝ4+ Ŝ2Ŝ3+ Ŝ3Ŝ4), |

several phrases need to be further revised. 1. much weaker molecular magnetic interactions... 2, magnetic susceptibility. (there can be only one static magnetic susceptibility in one system.) |

按三樓的建議，修改如下,原文的to 改為in order to ,意思是一樣的，只是順口一些，一般翻譯后還要讀一下，感覺通順為好！ The crystal structure of 1 shows that the coordination environments of each of the four Mn(III) ions in Mn4 unit are different and the bridging modes of each of two Mn(III) ions are not the same indicated the complicated magnetic coupling relations between Mn(III) ions . In order to qualitatively evaluate the magnitude of the magnetic interaction between manganese ions and simplify the coupling relationship between the four manganese ions,we introduced a coupling constant J.Further, in order to reduce the computational parameters and simplify the model ,the much weaker molecular magnetic interactions are not taken into account .According to tetrahedral arrangement of the MnIII4 system (Scheme 1),the magnetic susceptibility of the system (Equation 1) can be derived from the spin Hamiltonian Ĥ = -2J(Ŝ1Ŝ2+Ŝ1Ŝ4+ Ŝ2Ŝ3+ Ŝ3Ŝ4). |
