Spectroscopy is the branch of physics devoted to measuring and interpreting the interaction between matter and electromagnetic radiation. Every element and molecule produces a unique spectral fingerprint, enabling identification of distant stars, forensic trace analysis, and quality control in manufacturing.
These simulations let you generate atomic emission spectra, model absorption line broadening, fragment molecules in a virtual mass spectrometer, observe Raman scattering frequency shifts, and compute X-ray diffraction patterns from crystal lattices — all with interactive controls and physically accurate calculations.
