- Explains Raman scattering: photons lose energy when reflecting off surfaces, causing wavelength shifts that identify molecules.
- Describes CubeRaman: a DIY, 3D-printed spectrometer using a 532 nm laser, filters, and kinematic mounts with magnets.
- Highlights tests: raw diamond showed expected shift; ethanol and glass bottle tests revealed challenges with stray signals.
- Notes room for improvement: reducing stray light and using a narrower slit in the spectrometer.
