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.
The core product is FTIR spectrum search and analysis. Specialized workflows extend it; they do not replace the everyday library-search workflow.
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
Keep the evidence connected to the conclusion
Candidates, characteristic peaks, supporting literature and unresolved evidence remain inspectable around the result.
My Analyses & Results
Useful tools stay visible instead of being buried inside one workflow.
Use the tool that matches the data you actually have — an 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.

Find Spectrum
Find a reference record directly by spectrum number, CAS number, IUPAC name or product name.
Quick referenceIR Frequency Table
Look up characteristic regions, functional groups and peak pages while interpreting spectra.
CompatibilitySupported Formats
Check the current instrument, interchange and numerical file types supported by the upload pipeline.
When the job needs a dedicated analytical deliverable.
Professional services are submitted through Online Requirement. They are separate from the normal spectrum-search workstation.
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.

Move into a dedicated workflow when one spectrum is not enough.
Research, QC and formulation workflows are built on the same FTIR foundation, with interfaces designed for their specific analytical jobs.

Research Batch
Compare groups and replicates, inspect multivariate patterns and peak differences, and export numerical results.

QC Consistency
Compare incoming materials against a qualified baseline with spectral, distance and peak-difference evidence.
Open QC Consistency
Formulation Analysis
Build evidence across staged experiments, review the next analytical step and refine component hypotheses over time.
Open Formulation AnalysisUse FTIR.fun from the computer around your instrument.
FTIR.fun is not limited to a normal office browser. Use the web app, the FTIR Launcher, a Gateway connectivity path for restricted instrument PCs, or software integration 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.
