|The Forensics by Raman Library
is a collection of 175 Raman spectra of controlled substances, common contaminants, and
"cutting" agents. To create this library, the compounds were excited with a
Nd:VO4 laser (1064 nm) using a laser power of 100 mW measured at the sample. The compounds
were measured in glass containersa common practice with Raman analysis. The spectra
were then saved in Raman Shift format.
in this high resolution library were originally acquired at 4 cm-1 spectral
resolution (data points every 2 cm-1).
This library is designed to allow fast and easy
identification of common street drugs, such as methamphetamine, as well as impurities and
other agents that are typically found in illegal drugs. The library is particularly suited
for use by law enforcement personnel and forensic laboratories, as well as those in the
