MestReNova Manual

Significance of Topic

Modern NMR and LC/GC/MS data analysis demand intuitive, reproducible, high-throughput processing with minimal manual intervention. MestReNova’s unified, cross-platform environment transforms raw data into publication-quality spectra by automating format recognition, processing, analysis and reporting. Its WYSIWYG interface, advanced algorithms and scripting support address routine and complex analytical challenges, making it invaluable for research, QA/QC and industrial laboratories.

Objectives and Overview

MestReNova 15 integrates nuclear magnetic resonance (NMR), liquid and gas chromatography-mass spectrometry (LC/GC-MS) into a single user-friendly package. Key goals are to simplify raw-data import, offer one-click automatic processing (FT, phasing, baseline correction), and provide powerful tools for peak picking, deconvolution, integration, multiplet analysis, automated assignment and prediction. The software supports both time-domain and frequency-domain workflows and accommodates 1D, 2D and arrayed experiments.

Applied Methodology and Instrumentation

• Supported NMR formats: Bruker, Varian, JEOL, Agilent, Philips, Galactic, JCAMP-DX, ACD-Labs, etc.
• Supported MS formats: AB Sciex, Agilent, Bruker, Waters, Thermo, mzXML/mzData, NetCDF.
• ElViS optical spectroscopy: PerkinElmer, OPUS, JCAMP-DX.
• System requirements: Windows 7–11, macOS X 10.13+, major Linux distributions; 1 GHz CPU, 2 GB RAM recommended.
• Scripting: JavaScript-based API for automation, custom reports, batch processing and event hooks.

Main Results and Discussion

• Real-time Frequency-Domain Processing: Interactive apodization, zero filling, linear prediction, FT, phase and baseline correction with live previews.
• Automatic Phase & Baseline Corrections: Multiple algorithms (Global, Whitening, Metabonomics-optimized, Whittaker smoother) yield flat baselines and accurate absorptive lines without artifacts.
• Peak Picking & Deconvolution: Global Spectral Deconvolution (GSD) resolves overlapped multiplets, enables solvent/impurity identification and synthetic spectra generation.
• Multiplet Analysis: Auto-detection, J-tree display, first-order deconvolution-based J-value extraction, customizable reporting templates.
• Integration & Quantitation: Sum, edited sum, GSD-based integration, custom and predefined regions, automatic assignments for qNMR workflows.
• Covariance NMR: Direct, indirect and generalized methods boost resolution along the indirect dimension, reconstruct unsampled data and reveal long-range correlations.
• Reference Deconvolution & Resolution Enhancement: Post-acquisition strategies to shrink linewidths, correct instrumental lineshape distortions and enhance weak couplings.

Benefits and Practical Uses

• One-click import and processing streamlines routine 1D/2D NMR and MS analyses.
• Batch processing with saved templates ensures consistency across large data sets.
• Automated peak classification, assignment and prediction accelerate structure elucidation and verification.
• Customizable layouts, headers, footers, graphics and reporting templates support publication-ready figures.
• Scripting API and event hooks enable integration into laboratory information systems and advanced workflows.

Future Trends and Possibilities

Enhanced spectral editing, 3D quantitative NMR, AI-driven assignment and pattern recognition, support for non-uniform sampling (NUS) reconstruction, derivative processing, and GPU-accelerated algorithms promise to further reduce acquisition times, improve sensitivity and automate complex multidimensional analyses.

Conclusion

MestReNova 15 delivers a comprehensive, modern platform for NMR, LC/GC-MS and optical spectroscopy data processing, blending ease of use with advanced algorithms. Its real-time, automated workflows, graphical interface and scripting flexibility make it a vital tool for chemists, biochemists and QA/QC specialists aiming for rapid, reproducible and high-quality analytical results.
