FT-IR Activities and Exercises
The structures of 12 molecules (drawn in ChemSketch) are given. The corresponding FT-IR spectra are given, in scrambled order, in a SoftChalk slideshow. With interactive SoftChalk labeling activities, the user matches functional groups/chromophores to spectral peaks/bands. Finally, with SoftChalk labeling exercises the user identifies each spectrum. Detailed feedback is given for each answer. IR charts are provided.
Links to simulations which demonstrate the relationships of functional groups/chromophores/bonds to the frequencies of IR radiation they absorb, the types of vibrations produced by each absorption, and the spectral peaks/bands that result from each absorption are given.
