IR Spec Check is designed for organic chemists and students to quickly analyze absorbance peaks from an infrared spectroscopy graph. IR Spec Check recognizes over 75 absorbance frequencies and matches frequencies with possible R-groups. IR Spec Check's ranking system displays R-Groups based on how accurately your peak falls into the frequency ranges of each result.

Using IR Spec Check is easy! Just enter a wavenumber (cm-1). The results include what bond is responsible for each absorbance. The text displays what type of R-group is absorbing at the frequency.
