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.

Good first version

It's good to finally see some spectroscopy applications in the Apps Store. This one is a good first start. It's easy to use, but I would like to make a couple of suggestions that would make the app outstanding. Entering a vavenumber and getting suggested structural correlations can be very helpful, but it would be more useful to also offer confirmation bands to the user. This way, functional groups with similar wavenumbers can be more readily distinguished. Also, links to relevant spectral references (e.g. wiki?) would benefit users seeking mroe information. If the developers really wanted to push the application, they could also include a way to import spectra in some commonly available format so the range of the suggested matching band is superimposed over the actual experimantal spectrum!

Needs more character peaks

There is no easy way to determine what peaks this software is capable of identifying. There needs to be a reference table that lists all of the peak number associations. I have no way of knowing whether or not this supports sulfur chemistry... in addition to many, many other character peaks.

It would also be nice, if at the very least, I could add my own data into the program.

Too simple

I checked the app for factual accuracy, and didn't find any errors. However, developer needs to add a lot of features, such as the ability to input lineshape info (sharp, broad, weak, strong). Also there should be some way of dealing with features such as the aldehyde C-H doublet, or the various multi-peak aromatic bending modes.
