Overview
From the Leader in Spectral Data
World's Largest IR Spectral Library (ATR-IR, FT-IR, NIR)
Quality data. Results you can rely on.
When it comes to spectral data you need comprehensive data you can trust. Wiley's KnowItAll IR Spectral Library offers access to over 339,000 infrared spectral records* —the world's largest collection of high-quality infrared spectra including the renowned Sadtler databases.
- Broad coverage with access to over 150 databases covering a wide range of compounds. From organics and inorganics to application-focused data, we’ve got you covered!
- Along with spectra, records contain physical properties and structures when available
- Increase both the speed and likelihood of identification with a comprehensive dataset
- Cost-effective way to access an extensive and proven collection of spectral databases
* This library contains over 339,000 spectral records including: 249,285 unique spectra, 83,495 subset spectra, 7,710 augmented spectra.
Applications
This collection is an essential tool for the identification, classification, and verification of unknown compounds by IR spectroscopy in a wide range of applications such as polymer/materials, environmental, forensics/toxicology, pharmaceutical, biotech, automotive/aerospace, food/cosmetics, and many more.
Trusted data from a trusted source
Wiley is an authoritative source for spectral data. Their renowned Sadtler databases were processed according to rigorous protocols to ensure they are of the highest quality. These qualification procedures start at data acquisition and continue throughout the database development process. Any data acquired from trusted partners is thoroughly vetted before inclusion in our collections.
