本文介绍了几种用于观察液体和气体中的拉曼散射的简单实验装置。通常，这些设置不涉及超过一个小型（便携式）基于CCD的光谱仪（无扫描），两个镜头和一个便携式激光器。一些扩展包括一个便宜的分束器和一个滤色器。我们避免在所有设置中使用陷波滤波器。这些系统代表了一些最简单但最先进的拉曼光谱仪，用于教学/演示目的，并在各种情况下产生高质量的数据;其中一些传统上被认为具有挑战性（例如，同时检测斯托克斯/反斯托克斯光谱或气体的拉曼散射）。我们展示了用这些装置获得的数据的例子，并强调了它们对理解拉曼光谱的价值。我们还提供了一个直观的和非数学的介绍拉曼光谱激发实验结果。
Several simple experimental setups for the observation of Raman scattering in liquids and gases are described. Typically these setups do not involve more than a small (portable) CCD-based spectrometer (without scanning), two lenses, and a portable laser. A few extensions include an inexpensive beam-splitter and a color filter. We avoid the use of notch filters in all of the setups. These systems represent some of the simplest but state-of-the-art Raman spectrometers for teaching/demonstration purposes and produce high quality data in a variety of situations; some of them traditionally considered challenging (for example, the simultaneous detection of Stokes/anti-Stokes spectra or Raman scattering from gases). We show examples of data obtained with these setups and highlight their value for understanding Raman spectroscopy. We also provide an intuitive and nonmathematical introduction to Raman spectroscopy to motivate the experimental findings.
