Raman spectra

Vibrational modes of molecules

Depends on atomic mass, bond lengths, bond strength, configuration, etc…

Unique spectrum for each molecule

* Raman Fingerprints: Chemical detection with very high confidence level

Future Directions: • Develop Raman van/truck• UV / NIR systems (invisible /Eye safe)• Combined Raman + LIBS + LIF

sensors• Miniature systems for Rover• Raman Lidar (Environmental

monitoring)• Small portable system for Geologist• Remote Underwater Raman system

* Micro-Raman (Improve detection limits by using Nanoparticles, Nanofilms, special substrates). Study of biological processes, chemical reactions etc…

• Need for Material Synthesis lab (in the future)
