求名詞翻譯及其特性

Question

1. 1- 4 Dichlorobenz
2. Naphthalene
以上2種各為何物？並想知道他們的性質 謝謝各位大大

Answer 1

1,4-Dichlorobenzene （1,4-二氯苯）     ChlorineNuclear Quadrupole Coupling Constantsin 1,4-Dichlorobenzene     Chlorine nqcc's in 1,4-dichlorobenzene were calculated on the B3P86/6-31G(3d,3p) optimized molecular structure.  The results are given in Table 1.  Structure parameters and atomic coordinates respectively are given in Tables 2 and 3.  Table 1.  Chlorine nqcc's in 1,4-Dichlorobenzene (MHz).      Calc.Expterimental    35ClXaa-72.51  Xbb39.27  Xcc33.23  ETA *-0.083     37ClXaa-57.14  Xbb30.95  Xcc26.19       * ETA = (Xbb - Xcc)/Xaa = (Xxx - Xyy)/Xzz.    Table 2.
