Overview

Work Smarter with SmartSpectra!
Identify faster with expanded compound coverage

Unlock a broader spectrum of possibilities with Wiley SmartSpectra Databases, enhancing your chemical compound coverage to ensure more accurate and comprehensive unknown identification.

The Wiley SmartSpectra Vapor Phase IR Database Collection provides access to an impressive 215,427 high-quality spectra.

Designed for use with Wiley’s KnowItAll IR Spectral Library collection, it can be used in unknown identification to expand your available chemical compound coverage and improve your analytical workflow. And because it's built using Wiley’s trusted databases and informatics tools, you can be confident the spectra are based on sound scientific principles and methods.

This ground-breaking database:

• Aids in the analysis of unknowns, especially for rarer compounds and materials, when a match cannot be found in the empirical databases
• Is useful for functional group classification and is particularly strong with rigid structures
• Is derived from Wiley’s high-quality, comprehensive empirical reference datasets, including Sadtler spectra 
• Covers of a wide range of compound classes for use across various application areas
• Includes useful metadata, such as physical properties and chemical structures, along with the spectra to narrow your spectral search results
• Is validated by Subject Matter Experts (SMEs)

As a knowledge company and leader in spectral databases, Wiley combines over 60 years of expertise in spectral data excellence with the most current machine-learning (ML) techniques to expand the chemical space available to you with the new Wiley SmartSpectra Databases.

So just how much can the SmartSpectra database expand your compound coverage?

The SmartSpectra database collection can help you identify spectra faster by expanding your chemical compound coverage. As you can clearly see below, the SmartSpectra data (red) augments the chemical space of the empirical data set (blue) to provide you with significantly increased compound coverage.

Applications

You can use this collection along with empirical databases to identify, classify, and verify unknown compounds by IR spectroscopy in various applications, such as: 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.

Additional information

When it comes to spectral analysis, the more data you have the better. This SmartSpectra library contains the following valuable metadata to help you narrow and refine your search results:

• Chemical Structure
• Chemical Name
• Exact Mass
• Formula

• IUPAC InChI/InChIKey
• Molecular Weight
• Nominal mass
• Spectrum/Structure Validation Score

Validation

To generate this SmartSpectra database, Wiley Science Solutions used an AI-powered spectrum prediction engine based on its high-quality empirical spectral databases. Wiley then conducted studies by SMEs to validate results from the SmartSpectra library.

From these studies, the SMEs concluded that the library characterizes unknown spectral functional groups and performs well when searched against with sample spectra. SMEs suggest optimal workflow for SmartSpectra libraries is to use it when the empirical library yields low hit quality index (HQI) scores, poor matches, or no matches to help users classify and determine the structural characteristics.

See our validation study.

While Wiley has the largest commercially available library of extensive and high-quality empirical datasets, the total coverage is significantly smaller than the overall chemical space in use by chemists, life scientists, and materials scientists – i.e., the total number of possible molecules and compounds within a set of elements and rules. Augmenting our empirical coverage within the bounds of a model (the chemical space of the underlying training set) is a strategy to help improve overall available compound coverage for unknown identification, especially for rarer compounds and materials.

Predicted libraries, particularly when constructed from extensive and high-quality empirical reference datasets such as Wiley’s extensive spectral collections (including premium Sadtler spectra), demonstrate performance levels closely approaching that of empirical datasets of measured spectra. Consequently, they can be effectively integrated into the analytical qualification workflow.
