Open Specy


More than 350 people have used Open Specy to analyze, share, process, and identify their Raman and IR spectra.


To use the tool upload a csv file to the upload file tab. The file needs to be a csv with one column named -Wavelength- (in units of 1/cm) and another named -Absorbance-. You can smooth your data using an SG filter, baseline correct your data using the polynomial order of iModPolyFit, and restrict the wavelength range for the match. The result will be compared to an internal Raman or FTIR spectra library. The strongest 100 matches along with your uploaded or processed data will be presented in an interactive plot and table.

About the reference spectra

Reference spectra was sourced from open access resources online, peer reviewed publications, and corporate donations. In the future, spectra that is uploaded to the tool will be incorporated to the reference library to make it even better.

Contribute spectra

To share spectra upload a file to the upload file tab. If you selected Share a copy of your spectra will be sent to the Community Data Warehouse on Open Science Framework. To add additional metadata, fill in the avaliable metadata fields on the right hand side and click -Share Data-. The spectra file that you uploaded along with your responses will be copied to the a -With Metadata- subfolder at the link below. All shared data holds a Creative Commons Attribution-NonCommercial License 4.0.
