ARaman Agent Monitoring System (RAMS) is a technique which exploits Raman scattering to provide stand-off detection
and identification of toxic chemicals such as chemical warfare agents and toxic industrial chemicals deposited on the
ground surfaces. The RAMS collects counts on photons emitted by an agent on a surface through a telescope and displays the
result on a spectrograph. Raman scattering occurs when light interacts with a molecule. The molecule vibrates and scatters
wavelength shifted light. The wavelength shifts and their associated intensities are dependent on the size, shape, and bond
strength of the molecule creating, thus, a distinct spectral signature for the associated chemical. In this research, we measured
toxic chemicals with a RAMS, a 248 nm mobile Raman spectrometer, and analyzed Raman spectral signatures of Raman
signals of that chemicals. These results can assist in selecting unique molecular markers for each chemical to allow real-time
detection and identification of them in ground environments in moving.
