ftir.funWelcome to ftir.fun！
ftir.fun is a professional 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 comprehensive qualitative analysis references to support professional infrared spectral interpretation.
Our platform offers both pay-per-use and subscription-based access, serving individuals and organizations that require accurate infrared spectral analysis, including researchers, analytical scientists, forensic professionals, university faculty, and students. Our services are commonly applied in 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, together with AI-driven peak assignment and molecular structure analysis, providing users with 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.
Our objective is to provide powerful analytical tools while clearly defining the scope and limitations of the available data.
We are committed to data security, user privacy protection, and lawful, compliant operations.
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 is a retrieval method that compares the overall similarity between sample spectra and standard spectra, ranking results from high to low similarity. During the process, the peak heights of the samples are quantified to enhance efficiency. This method is relatively quick, taking 10 to 20 seconds, and is free for both visitors and registered users for unlimited use, although its accuracy is not very high. However, it is sufficient for general use.
Based on pre_search results, Advanced Mode Search obtain more accurate analytical results through comprehensive curve shifting comparisons, feature peak retrieval, fingerprint region retrieval, and cross-validation.This type of search requires extensive calculations and takes longer, approximately 50 to 80 seconds, but it offers higher accuracy. Additionally, this search provides comprehensive result analysis and discussion of characteristic peak assignments, which are not offered in Simple Mode.
Leveraging expert analysis, your prior knowledge, and analytical goals, we use knowledge graphs and neural networks to predict the relationships between peaks and functional groups, supported by the latest literature for accurate insights.Our NEO4J database currently contains over 5 million entries related to substances, groups, chemical bonds, characteristic peaks, and more. We also train substance MACCS and characteristic peaks based on standard spectra from the spectral library, which facilitates more accurate analysis of infrared spectra. This analysis typically takes more than three days.
It is best to upload a CSV or Excel file exported from the infrared spectroscopy device, which should have two columns: one for wavenumber (cm⁻¹) and the other for absorbance or transmittance. RAW .spa files are also acceptable. If you only have raw data from devices like BRUKER or SHIMADZU, you can upload those as well; the backend will process them, but it may take about 1 hour to complete the processing, after which you will be notified via the website or email. If you only have images, PDFs, etc., the backend can also attempt to extract spectral data, but success is not guaranteed.
Please enter the IPUAC_NAME, SMILES, or CAS of the substance you want to search for. It is recommended that you first search on the PUBCHEM website (https://pubchem.ncbi.nlm.nih.gov/) to obtain accurate search keywords. If you do not have this information, you can also enter the product name, and the backend will attempt to find the substance using its synonyms.
