If you were able to monitor the progress of this reaction via IR spectroscopy, describe what the spectra would look like as the reaction proceeds. (a) Explain how an IR spectrum of the starting material would look different than the product and (b) based on that, what would you expect the IR spectrum to look after the reaction is 50% complete? Assume that only vanillin and vanillyl alcohol show up in the IR spectrum.

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
