Why thinfilm absorption spectrum redshift compared with solution spectrum?
5 answers
The redshift observed in the absorption spectrum of thin films compared to solution spectra can be attributed to various factors. In thin films, the enhancement of coplanarity of polymers leads to the existence of low-energy species, causing a different behavior in the excited state. Additionally, the morphology of polymer chains in solution, influenced by factors like solvent and concentration, affects the conjugation lengths of the chains, ultimately leading to a red shift in absorption spectrum. Furthermore, studies on solid solutions have shown that the transfer of excitons between different tetrahedra along specific crystal axes contributes to the concentration-dependent spectral position of excitonic bands, resulting in a redshift in the absorption spectra of thin films.

What is Gibbs Microcanonical Ensemble?
5 answers
The Gibbs Microcanonical Ensemble refers to a thermodynamic ensemble where the entropy is defined based on the total number of states with energies equal to or less than a specified energy E, as opposed to the Boltzmann entropy which is determined by the density of states at E. This ensemble is crucial for systems with bounded energy spectra, as it avoids the issue of negative absolute temperatures that can arise with the Boltzmann entropy in such cases. While the Gibbs entropy complies with fundamental thermodynamic relations, it does not exhibit the additive property expected for large systems composed of weakly coupled subparts, unlike the Boltzmann entropy. The Gibbs Microcanonical Ensemble plays a significant role in understanding the thermodynamic behavior of systems with constrained energy levels and provides insights into the dynamics of integrable Hamiltonian systems.
