Better FTIR answers, backed by evidence.
Search reference spectra, analyze unknowns, inspect ranked candidates and characteristic peaks, and bring spectral and literature evidence together in one practical FTIR platform.

Start with a spectrum. Search the library. Build a better-supported answer.
Upload an FTIR spectrum to search the reference library and inspect the evidence. For grouped studies, routine QC or formulation work, dedicated tools are available when you need them.
Library CoverageBrowse current reference-library coverage by material domain.Spectrum Search & Analysis
Upload an unknown spectrum, retrieve relevant references, inspect ranked candidates and spectral agreement, and continue into evidence-supported interpretation.

Verify a Suspected Material
Start from a stated material hypothesis and check whether the available FTIR evidence supports it.
Verify a material
Review the evidence behind each result
Review candidate matches, characteristic peaks, supporting literature and any unresolved points alongside the conclusion.
My Analyses & Results
Choose the tool that fits what you have.
Start from a spectrum image, a known reference name, or a peak position.
Recover numerical spectrum data from a figure or image.
Crop the plot, calibrate its axes, trace the curve with automatic, color or manual methods, preview the spectrum and export CSV for further analysis.

Check the instrument, interchange and numerical file types currently accepted for analysis.
When the job needs a dedicated analytical deliverable.
Use Online Requirement when you need a literature-backed peak assignment, a custom comparison, complex-sample analysis or another manual FTIR service.
Academic Peak Assignment, customized two-spectrum comparison, complex sample analysis and other IR support
Choose the service, upload the relevant evidence and describe the question to be answered. Academic Peak Assignment is the dedicated literature-backed peak-attribution service for known compositions.

Find the FTIR workflow built for your organization.
Universities, QC laboratories, R&D teams, training providers, laboratory-software companies and scientific-information platforms use FTIR differently. Choose your organization to see what established tools already do, what FTIR.fun adds, and how to use or integrate it.

Turn statistical differences into scientific interpretation
Keep replicates and group statistics, then connect PCA or distance patterns back to changed bands, peak differences and supporting literature evidence.
Explore Research & Academia
Go beyond PASS/FAIL when a sample is different
Use qualified history and statistical comparison to find abnormal regions, then continue into peak-level interpretation and evidence for investigation.
Explore QC Evidence
Explain what changed as materials and formulations evolve
Keep controls, process stages and formulation changes together, then connect spectral differences to interpretable hypotheses and domain-specific evidence.
Explore R&D & Formulation
Build practical FTIR training around real spectra
Let learners make a real analytical judgement before revealing the reference explanation and evidence, with reusable cases that can be adapted to your course or industry.
Explore Training & Education
Add FTIR expertise without building it yourself
Embed reference search, evidence-backed interpretation, research or QC context, Image/PDF → spectrum and custom FTIR results through REST, OpenAPI or MCP.
Explore Laboratory Platforms
Make FTIR figures computable and comparable
Turn published figures into numerical spectra, preserve DOI and figure provenance, compare them with experimental FTIR and carry peak-level evidence into downstream research workflows.
Explore Literature PlatformsUse FTIR.fun from your instrument computer or another connected device.
Open FTIR.fun in a browser, use the FTIR Launcher on supported instrument computers, use the Gateway where general internet access is restricted, or connect your software through API and MCP.

The result comes first. The evidence stays available.
Reference retrieval is central to FTIR.fun. The result can also retain characteristic peaks, candidate comparisons, literature support, conflicts and recommended confirmation where they are useful.
Start with the spectrum you already have.
Upload a file, find a known reference, or recover numerical data from a spectrum image.
