Excited-state transitions are ideal tests, but optical spectra often have broad, less-standardized bands. Full line shapes require anharmonic, vibronic, and environmental effects. Closer theory–measurement work would benefit both fields.

Researchers Simulate Molecule Spectra At Any Temperature Rapidly
After initial classical molecular dynamics computations taking on the order of hours, vibronic spectra at nonzero temperatures can now be calculated in seconds. This advance stems from a combination of coherence thermofield dynamics with the single-Hessian approximation for weakly anharmonic systems. The method accurately reproduces key spectral features like hot bands and broadening without extensive additional computation.
