结构化学是研究原子、分子和晶体的微观结构以及它们和性质之间关系的科学,包括它们的电子结构和几何结构。电子结构主要指描述电子运动规律的波函数,即原子轨道和分子轨道,通过轨道相互作用了解化学键的本质。几何结构主要指分子或晶体中原子空间排布的立体结构。一切化学现象都是原子核和外围电子的重新排列和组合,即都与原子、分子和晶体的电子结构和几何结构有关。随着近代科学的飞跃发展,结构化学在化学科学中的基础地位的作用越来越明显,它与无机化学、有机化学和分析化学密切相关,通过结构化学课程的教学将进一步加深学生对这些学科的认识和理解。 Structural chemistry is a science that studies the microstructures of atoms, molecules, and crystals, as well as the relationship between them and their properties, including their electronic and geometric structures. The electronic structure mainly refers to the wave function describing the law of electron movement, that is, the atomic orbitals and the molecular orbitals, and understanding the nature of the chemical bonds through the orbital interaction. Geometrical structure mainly refers to the three-dimensional structure of atoms or atoms in a crystal. All chemical phenomena are rearrangements and combinations of nuclei and peripheral electrons, all of which are related to the electronic structure and geometry of atoms, molecules and crystals. With the rapid development of modern science, structural chemistry plays a more and more important role in chemical science. It is closely related to inorganic chemistry, organic chemistry and analytical chemistry. The teaching of structural chemistry courses will further deepen the students’ understanding of these disciplines Understanding and understanding
