Spectral Libraries

Spectral libraries are curated collections of detailed digital fingerprints of substances, often used in fields like chemistry and forensic science. Each fingerprint, called a spectrum, captures how a substance absorbs or emits light or other signals at different energies. By comparing an unknown sample's spectrum to these reference profiles, scientists can identify or confirm the presence of specific compounds quickly and accurately. Think of spectral libraries as comprehensive reference manuals for recognizing materials based on their unique spectral "signatures," aiding in tasks like drug identification, environmental analysis, and quality control.
