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) and hit "go". The icon for each result shows what bond is responsible for the absorbance. The text displays what type of R-group is absorbing at the frequency.
