I think that wouldn't necessarily work once you get to the right wavelengths for it to start interacting with the organic bases of the paints. There's only so much you can do when someone shoots an infrared laser at the resonant frequency of a C=C double bond.

Wasn't that 1500 whatever-the-unit-was? Below 1000 whatever-the-unit-was was the fingerprint bands, 3400ish whatever-the-unit-was was the O-H bonds, 3100ish whatever-the-unit-was was N-H bonds, 2900ish whatever-the-unit-was was the triple-to-C-H bonds, etc.

Ugh. The lab portion for that was so tedious. We would have to sketch the expected resonance patterns by hand for a bunch of different molecules. I loved the simplicity of the hydrogen bond nuclear resonance imaging so much more.

uh, frequency is Hz (hertz) unit to my memory. if that's what you're using

It could also be scaled (THz) or when working with light given as a wavelength (nm) and sometimes even photon energy (eV).
