About FTIR.fun
FTIR.fun is a professional multilingual online infrared spectroscopy database, providing efficient and reliable infrared spectral analysis and interpretation services for users worldwide. FTIR.fun is designed to complement rather than replace established commercial infrared spectral databases, offering professional and in-depth qualitative analysis references.
Unlike traditional commercial infrared spectral databases, FTIR.fun focuses on flexible usage, rapid updates, and deeper spectral interpretation rather than rigid, provenance-focused reporting.
Flexible Access
Pay-per-use and subscription-based access, eliminating the need for expensive one-time purchases.
Rapid Updates
Continuously updated reference spectra, aiming to cover newly emerging substances and products as early as possible.
AI-assisted Analysis
Advanced AI-assisted peak analysis and cross-validation using multiple algorithms, going beyond simple similarity scores.
If your priority is the interpretation of infrared spectra and the inference of sample composition and functional groups, rather than generating highly standardized reports based on strictly traceable reference spectra, FTIR.fun can serve as a reliable analytical assistant.
Our platform serves individuals and organizations that require accurate infrared spectral analysis, including researchers, analytical scientists, forensic professionals, university faculty, and students. Typical application scenarios include material research and development, forensic evidence identification, product failure analysis, foreign material identification in manufacturing processes, and trace substance composition analysis.
Our core strength lies in a dynamic and continuously expanding infrared spectral library, which is regularly updated using data from public sources and user contributions to reflect newly characterized compounds and materials. We enhance infrared spectral matching performance through customized similarity-matching algorithms combined with AI-driven peak assignment and molecular structure analysis, providing more comprehensive and accurate qualitative interpretation support. In addition to automated analysis tools, FTIR.fun may offer customized services involving expert-assisted manual analysis of complex or atypical spectra upon user request.
Infrared spectral data uploaded by users may be incorporated into our database to improve future matching and analysis performance and may be used as part of our commercial services. Compared with mature commercial databases, some infrared spectral entries may contain limited information on sample preparation. They are intended to support technical interpretation and analytical insight during the evaluation process, but should not be used as the sole or direct basis for arbitration, expert determination, or other formal decision-making purposes.
We are committed to data security, user privacy protection, and lawful, compliant operations. Our objective is to provide powerful analytical tools while clearly defining the scope and limitations of the available data.
All financial transactions are processed through secure and trusted payment channels, ensuring safe and reliable access to our services for customers worldwide.

Frequently Asked Questions (FAQ)
Simple Mode Search uses a hash-based filtering algorithm to suppress baseline drift and focus on major absorption peaks. Results are ranked from high to low spectral similarity. AI-based peak interpretation is not available in this mode.
Based on hash-filtered candidates, Advanced Mode Search applies curve shifting, characteristic peak matching, fingerprint region analysis, and cross-validation to achieve more accurate and reliable results.
Exclusive to paid users, this feature uses a dedicated batch-processing pipeline to submit and analyze multiple spectra simultaneously, significantly improving efficiency. It is ideal for high-throughput and time-sensitive workflows, such as third-party testing laboratories.
We support common instrument formats such as .spa, as well as exported data formats including .csv and .txt. For exported files, please ensure they contain only two columns (wavenumber and absorbance or transmittance), without headers, units, or additional annotations, otherwise parsing may fail.
Enter the compound's IUPAC name, SMILES, or CAS number. We recommend searching PubChem first to obtain accurate identifiers. If these are unavailable, you may also enter a product name, and the system will attempt to locate the compound using synonyms.
New users receive trial access. Additional usage can be obtained through pay-as-you-go purchases or monthly and annual subscriptions. Subscription users enjoy unlimited usage.
Payments can be made via hosted checkout, PayPal, or invoice links issued through Wise. Multiple currencies are supported, including USD, EUR, GBP, and CNY. Taxes and invoices are handled in compliance with applicable regulations, typically processed automatically by the payment platform.
