    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.

      chemist was my weak point at uni. and I’m too tired to look that up, what’s the frequency. I want to check if there are materials that can reflect it.

      the coating doesn’t have to be organic, a thin metallic coating might reflect the laser.

      I’m not giving an expert opinions. but I’m personally betting that any laser weapon will be useless within weeks or days.

      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.
