What happens after I drop a Raman file?
The measurement file is converted into a Raman shift versus intensity graph. From there, the workspace helps you review preprocessing, peak fitting, and material metrics.
Raman Spectroscopy
Raman Analysis
Convert Raman spectroscopy files into graphs, then review preprocessing, peak fitting, and material metrics in one workflow.
Supported formats
.txt, .csv, .dat, .asc, .tsv
Available analysis features
- Preprocessing
Review baseline and spike-removal settings before using the processed Raman signal for downstream analysis.
Preprocessing changes the signal used downstream; compare raw and processed spectra before trusting fitted peaks or material metrics.
- Peak Fit
Fit selected Raman peaks and review center position, FWHM, area, and fit quality together.
Peak-fit values depend on selected peak windows, baseline quality, model choice, and residual behavior; review fit evidence before reporting FWHM or area.
- Material Metrics
Use user-provided reference constants to review stress, crystallinity, D/G ratio, or temperature-related Raman metrics.
Material metrics depend on user-provided reference constants and selected peaks, so treat them as review candidates unless the constants are validated.
What this tool can review
- Spectrum visualization
Load Raman shift and intensity data and convert it into a graph for quick peak and background review.
- Preprocessing
Adjust baseline and spike-removal conditions to review the processed Raman signal before fitting.
- Peak Fit
Fit selected Raman peaks and review center position, FWHM, area, and fit-quality evidence.
- Material Metrics
Review Raman-derived material metrics using user-provided constants where those values are available.
Typical use cases
- Review Raman spectra before peak fitting or report preparation.
- Compare baseline and spike-removal effects on processed Raman signals.
- Fit selected Raman peaks and review FWHM, area, and quality evidence.
- Use user-provided constants to inspect material-related Raman metrics.
FAQ
Can I control preprocessing before fitting?
Yes. Preprocessing lets you review baseline and spike-removal effects before using the processed Raman signal for fitting and metrics.
How are my measurement files handled?
Files uploaded to this analysis tool are processed in the current browser session for graph conversion and analysis. The tool does not send files outside or save them without user permission.
Supported workflow
- Graph Conversion turns Raman measurement files into Raman shift versus intensity views for spectrum review.
- Preprocessing reviews baseline and spike-removal effects on the processed Raman signal.
- Peak Fit estimates peak center, FWHM, area, and fit quality for selected Raman peaks.
- Material Metrics uses user-provided constants where needed, so interpretation depends on the supplied reference values.
