InterSpin: Integrated Supportive Webtools for Low- and High-Field NMR Analyses Toward Molecular Complexity

Area of Science:

• Analytical Chemistry
• Biophysics
• Materials Science

Background:

• Nuclear Magnetic Resonance (NMR) spectroscopy is crucial for analyzing molecular structures.
• Handling broad spectra from solid-state or low-field NMR presents challenges.
• Efficient signal assignment is key for diverse applications in food, materials, and environmental science.

Purpose of the Study:

• To introduce InterSpin, a comprehensive resource for NMR data analysis.
• To provide accessible web tools and a database for advancing NMR signal assignment.
• To support the analysis of small molecules to macromolecules across various NMR techniques.

Main Methods:

• Development and evaluation of preprocessing web tools: sensitivity improvement and peak separation.
• Creation of the InterSpin Laboratory Information Management System (SpinLIMS) database for standard spectra.
• Implementation of molecular assignment tools: SpinMacro for macromolecules and InterAnalysis for small molecules.

Main Results:

• Two novel preprocessing tools enhance signal-to-noise ratio and resolve overlapping peaks.
• SpinLIMS database provides extensive spectral data searchable under various conditions.
• SpinMacro and InterAnalysis facilitate accurate assignment of macromolecules and small molecules, respectively.

Conclusions:

• InterSpin provides integrated, freely accessible tools and a database to advance NMR signal assignment.
• The system supports diverse applications, from small molecules to macromolecules, in solid and solution states.
• Database interoperability through SpinLIMS client software promotes data sharing and scientific discovery.
