Demo data

Preset system

DMPO–OH

Single component · 1:2:2:1 splitting

An educational simulation generated from preset parameters, without model inference. Review real samples against experimental conditions and controls.

Examples include a bundled file and synthetic spectra. See each sample for its source and notes.

03 / Built around evidence

See the result.
Review the evidence.

Research needs more than an AI suggestion:
it needs an analysis you can inspect, compare and review.

Compare signal and simulation

Compare the signal, simulation and residual to identify both agreement and unexplained features.

Keep the parameter details

Trace interpretations back to g factors, hyperfine couplings and linewidths.

Bring experimental context

Use candidates, controls and validation ideas to plan the next step in your research.

CONVERSATION PREVIEW

Can this spectrum identify a radical on its own?

Review spectral features alongside the experiment.

This demonstration uses a synthetic spectrum generated from preset DMPO–OH parameters. For real samples, review candidates against the spin trap, experimental conditions, controls and fit residuals.

Similar spectra provide a clue, but cannot establish a final assignment on their own.

From data to report, with fewer steps.

Keep the workflow connected and focus on your question.

Add context for your workflow: the spin trap and solvent for spin trapping, or material details for defect screening. Confirm measurement conditions, including microwave frequency.

Can I try it without uploading experimental data?

Yes. Explore four examples, including the bundled DMPO two-component file and a synthetic Perylene organic radical spectrum. View spectra, data notes and sample reports without signing up or uploading your own data. Use the workspace to analyze experimental data.

Which EPR / ESR data can I analyze?

Current workflows include single-, two- and three-component spin-trapping analysis with an automatic mode; candidate identification and fitting for directly detected, single-component organic radicals in solution; and oxygen-vacancy-related signal screening. Metal-center analysis is coming soon.

The direct-detection organic radical workflow excludes nitroxides and spin-trap adducts. Defect screening does not identify other defect types, and single crystals and non-oxides are not currently supported. Check the workspace guidance for the scope of each workflow.

Common upload formats include TXT, CSV, ASC, XLSX, EPR/EPRP and paired Bruker DSC + DTA files. Review fits and parameters, consult relevant literature and export reports after analysis.

Is an AI candidate assignment a final conclusion?

Review candidate assignments against experimental conditions, controls and differences between data and fits. Matching parameters and similar spectra provide clues, but do not replace scientific judgment.

How is my experimental data handled?

Upload and analyze experimental data in the workspace. See the privacy policy and terms for data processing and storage.

Do I need software? Can I use a phone?

EPRMind runs in a modern browser on computers, tablets and phones. Larger screens make detailed spectra and parameter comparisons easier to review.
