基于对形态学的详细研究（外部形态的演变和变化），晶面的表面微观形貌（螺旋和蚀刻图），内部形态（生长扇区、生长带和相关杂质分配）和完善（位错和其他晶格缺陷），通过晶体在无约束条件下的生长和生长后的历史，我们可以推断出晶体是如何生长的，以及通过何种机制生长的，以及生长参数经历了哪些波动。这些信息不仅有助于找到合适的方法来生长高度完美和均匀的单晶，而且有助于破译来自地球和太空深处的信件。它也是有用的区别合成天然宝石。在本章中，获得分子信息的可用方法进行了简要总结，并从天然矿物（金刚石，石英，赤铁矿，绿柱石，金云母）和合成晶体（碳化硅，金刚石，石英，绿柱石）中选择实际的例子来证明这种类型的调查的重要性。
Based on detailed investigations on morphology (evolution and variation in external forms), surface microtopography of crystal faces (spirals and etch figures), internal morphology (growth sectors, growth banding and associated impurity partitioning) and perfection (dislocations and other lattice defects) in single crystals, we can deduce how and by what mechanism the crystal grew and experienced fluctuation in growth parameters through its growth and post-growth history under unconstrained condition. The information is useful not only in finding appropriate way to growing highly perfect and homogeneous single crystals, but also in deciphering letters sent from the depth of the Earth and the Space. It is also useful in discriminating synthetic from natural gemstones. In this chapter, available methods to obtain molecular information are briefly summarized, and actual examples to demonstrate the importance of this type of investigations are selected from both natural minerals (diamond, quartz, hematite, corundum, beryl, phlogopite) and synthetic crystals (SiC, diamond, corundum, beryl).
