拉曼光谱已经成为石墨烯的表征和改性研究中必不可少的工具，在石墨烯的层数、缺陷表征，以及掺杂、堆叠、层间嵌入、环境影响等方面的研究起着非常重要的作用。拉曼成像不仅可直观的表征不同层石墨烯层数的空间分布，还可以表征石墨烯掺杂、形变引起的拉曼峰位、峰形变化的分布。

拉曼散射和荧光发射具有相似的起源，是两个相互竞争的过程。通常，激光光子与分子碰撞后一部分能量传递给分子振动（斯托克斯过程）。散射光子因而能量减小，相应的散射光表现为频率红移。不同的分子振动对应于不同的频率位移，从而给出分子的拉曼光谱，该光谱就蕴涵了该样品分子的特征信息。

拉曼是一种光散射现象，光子被物质分子或晶格散射后，能量发生了改变，这种能量改变与分子本身密切相关，反映了材料组成、结构等信息。不同的拉曼峰位对应于不同的特征基团。本文列举了一些常见的拉曼峰位所对应的特征结构。

麻醉品、高聚物、爆炸物、颜料以及生物残留都有各自特征且信息丰富的拉曼光谱，因此快速、无损的拉曼光谱仪也成为刑侦及法庭科学研究的理想分析工具。

在我们的日常生活中，颜料起着重要的作用，它被广泛应用于家具、塑料制品、纺织品、书籍和绘画艺术品的染色。由于颜料很难溶解于普通溶剂之中，因而对它们的鉴别存在很多困难。当样品数量极少，或者需要进行无损伤的研究时，这种困难就显得尤其突出，例如：在法医学实验室或者珍贵绘画艺术品的鉴别等领域。 拉曼光谱也已被证明是特别适合解决这些难题的分析方法。如今，产品识别、数据分析以及赝品鉴别等问题都可以利用拉曼光谱解决。这项技术已经成为解决所有这些难题的有力工具。

显微拉曼分析已经成为表面分析和固相颗粒分析中一项常规必备的实验手段。最新的自动化技术已经使得分析人员可以方便地研究表面污染物，分析表面结构。刑事侦查领域以及司法部门的研究人员对于核实某一表面上的爆炸物存在特别感兴趣，他们也关注于研究某种成分在爆炸物或易爆材料中的分布情况。 以前，用来提供此类信息的手段有有损伤性的色谱法、质谱法；还有AFM之类定性分析方法。然而，这些分析技术或者对样品是破坏性的，并且需要冗长的样品提纯过程，或者对样品特征的揭示很少，并且是间接性的表征。 比较而言，拉曼显微技术可以提供无损的、原位的、详细的特征光谱和分布信息。 本文报道了如何利用显微拉曼对含有两种典型成分三次甲基三硝基胺（RDX）和季戊四醇四硝酸酯（PETN）的某种爆炸物在表面上的存在进行表征。

The Raman spectra of elemental carbon materials are known to be sensitive to polymorphy. For hard carbon films, the spectra of amorphous and diamond-like carbons can be band-fit to separate the contributions of the "graphitic carbon" (G band) from the "disordered carbon" (D band). The spectral behaviour of carbon films has been empirically correlated with thin film physical properties such as hardness, durability, optical transparency, electrical conductivity, thermal conductivity and corrosion resistance, and can be of use for prediction of these properties without extensive alternative testing.

Non-destructive optical monitoring of chemical composition can be accomplished using Raman Spectroscopy. Raman spectra can be utilised to distinguish differences in chemical bond structures. This is particularly useful in applications where reactions could progress towards either a desired product or an undesired by-product. The Raman spectrum indicates when local conditions exist which favour one reaction path over another. This qualitative measurement can be developed into a tool to monitor process conditions.

Metal oxides, in contrast to most metals, are well known to be easily distinguished by their characteristic Raman spectra; their presence can be detected on a scale of micrometers with a Raman microprobe. Often, the various oxides of a particular metallic ion have significantly different Raman spectra, with even the degree of hydration of the ligated cation generating a tell-tale vibrational fingerprint. Thus, the diverse oxide forms of a variety of metals, including, for example, iron, nickel, lead, titanium, zirconium, molybdenum, copper, and vanadium, can be distinguished by a fast and non-destructive spectroscopic measurement. In practice, this allows the scientist or engineer to delineate the kinetics of oxidation of any of these species, observing where and when successive species are formed during the oxidation of a raw metal. For example, steel rust exhibits layers of several oxides of iron, including hematite, lepodocrocite, goethite,and magnetite, with the layer thicknesses and ordering dependent upon the composition of the steel, the conditions of the environment, and the duration of exposure.

For many years Raman spectroscopy has been applied to characterisation of polymers. However, the applications have tended to be research-oriented, rather than designed for routine analysis. With the revolutionary developments in Raman instrumentation, it is now possible to acquire spectra quite rapidly on equipment that is much more affordable and easier to use than in the past. The following will summarise how Raman spectroscopy has been used successfully for the study of polymers, and will indicate which effects can be monitored on a routine basis for industrial analytical purposes.

The phenomenon of diffusion has been known for centuries. For example,the ancients who dyed fabrics certainly noticed the leading edge of their turquoise dye propagating through their cotton cloth, and biologists have long been aware of osmosis through various membranes. With our century’s advances in engineered materials, scientists and engineers are now able to design diffusive layers to provide controlled rates and selectivity of diffusion. There are a number of applications of engineered diffusion in current technology. Some are medical: drug patches allowing sustained slow release of a pharmaceutical, and membranes are used in dialysis and various laboratory separation procedures. Similar to the use of drug patches is the agricultural use of slow-release nodules to provide sustained fertilisation of soil. Industrial production of chemicals and foodstuffs often depend on separations with various membranes. Other applications are of a less organic nature, as in the separation of gases by selective diffusion through membranes, and of ions through a solid, which might be part of a battery or other electronic device. Sometimes, diffusion is an undesirable phenomenon, as when we wish to store gases dissolved in a solid, and they can diffuse out over time, or when diffusion of oxygen into a semiconductor crystal can depreciate the performance of an electronic device.
