Efficient spectral analysis in MestReNova (Mnova) involves optimizing your workflow from data ingestion to final reporting. By utilizing keyboard shortcuts, automation tools, and customized templates, you can significantly reduce processing time while maintaining absolute data precision.
The ultimate workflow tips below are structured chronologically to help you master efficient 1D and 2D NMR spectral analysis. 🚀 Data Import & Navigation
Drag-and-Drop Ingestion: Skip navigating through nested file menus. Drag your raw experimental data folder or direct zipped fid files straight into the workspace to auto-load the spectrum.
The Multi-Z Zoom: Tap the Z key sequentially to switch zoom types. Pressing it once activates horizontal zoom, twice activates vertical zoom, and three times triggers box zoom. Press Esc to reset the cursor.
Intensity Control: Rotate your mouse scroll wheel upward to quickly scale up weak peaks. Roll it downward to scale down highly intense solvent peaks. 🛠️ Spectrum Pre-Processing & Referencing
Whittaker Smoother Baseline: Correct wavy, uneven baselines by clicking the baseline correction tool. Choose the Whittaker Smoother algorithm for the cleanest flat baseline results.
Quick Referencing: Zoom into your reference peak (e.g., TMS at 0.00 ppm or CDCl₃ at 7.26 ppm). Press the L key (or select Reference), click the top of the peak, and type in the standard solvent shift value.
Edit Blind Regions: Use the Cut tool (X) or the Blind Regions tool to hide heavily distorted areas or massive water/solvent signals that disrupt automatic multiplet analysis. 📊 Advanced Peak Picking & Integration
Toggle Peak Snap: By default, Mnova snaps directly to peak tops. Tap the Shift key once while using the Peak-by-Peak tool (Cmd+K / Ctrl+K) to disable snapping. This allows you to manually pinpoint un-resolved peak shoulders.
Global Spectral Deconvolution (GSD): Enable “Show Peak Curves” in the peak picking options. This uses GSD to automatically extract true chemical peaks from overlapping clusters or messy solvent envelopes.
Relative Integration: Drag over your signals using the I key to integrate. Set your primary target integral to 1 (or your known number of hydrogens), and all subsequent manual integrations will scale relatively. ⏱️ Workflow Automation & Reporting
