Drop a VAMAS, JCAMP-DX or two-column file on the chart. Read its peaks, the elements they could be, the components the file was fitted with, and the composition they give.
Draw a structure to predict its C 1s and O 1s lines from 2 089 molecules of the QM9 database, or compare 111 measured polymers with the prediction for their repeating unit.
Open a VAMAS, JCAMP-DX or two-column file to read its peaks, its fitted components and its composition, or draw a structure to predict its spectrum. The tool needs JavaScript, because every spectrum is read in your browser.
