本文综述了非传统的拉曼光谱技术，并讨论了这些技术在地球和行星科学中的应用现状和未来。时间分辨光谱学开辟了限制或利用发光效应的新方法，而基于相干反斯托克斯拉曼散射（汽车）或表面增强拉曼光谱学（Sers）的技术允许拉曼信号被显著增强，甚至降低到非常高的空间分辨率。此外，紧凑型便携式拉曼光谱仪现在经常在实验室外使用，甚至在不久的将来集成到两个前往火星的火星车上。
This article reviews nonconventional Raman spectroscopy techniques and discusses present and future applications of these techniques in the Earth and planetary sciences. Time-resolved spectroscopy opens new ways to limit or exploit luminescence effects, whereas techniques based on coherent anti-Stokes Raman scattering (CARS) or surface-enhanced Raman spectroscopy (SERS) allow the Raman signal to be considerably enhanced even down to very high spatial resolutions. In addition, compact portable Raman spectrometers are now routinely used out of the laboratory and are even integrated to two rovers going to Mars in the near future.
