Photochemistry governs every light-driven process in nature and technology. When a molecule absorbs a photon, it enters an excited electronic state that can trigger bond breaking, electron transfer, or energy emission as fluorescence. The Beer-Lambert law quantifies how light attenuates through absorbing media, while quantum yield measures the efficiency of photochemical conversion.
These simulations let you explore photon absorption and spectral transmission, measure fluorescence quantum yields, model TiO2 photocatalytic degradation of pollutants, trace the electron transport chain in photosynthesis, and predict UV weathering rates for polymers — all with real-time interactive controls grounded in established photochemical equations.
