Absorbance spectra are continuous rather than quantized in condensed phases
Absorbance spectra in condensed phases are fundamentally continuous due to environmental interactions, thermal fluctuations, and overlapping vibrational and phonon manifolds.
The claim addresses whether absorbance spectra are continuous in condensed phases. Quantum mechanics and spectroscopy principles establish that condensed phase environments (liquids, solids, dense polymers) cause significant inhomogeneous broadening and vibronic coupling, resulting in continuous absorption bands rather than discrete atomic-like lines. The retrieved papers discuss condensed-phase absorption spectra, optical line shapes, and band broadening (e.g., papers 4 and 5), consistent with the continuous nature of condensed phase spectra.
