Integrated computational strategies for UV/vis spectra of large molecules in solution

In recent years, the margin of interaction between computational chemistry and most branches of experimental chemistry has increased at a fast pace. The experimental characterization of new systems relies on computational methods for the rationalization of structural, energetic, electronic and dynamical features. In particular, novel computational approaches allow accurate estimates of molecular parameters from spectroscopic optical observables, giving rise to synergic interactions between experimentalists and theoretically- oriented chemists. Our main objective in this tutorial review is to delineate the degree of advancement of possible integrated computational approaches to the interpretation of optical spectroscopies, with an accent on large molecules in solvated environments, based on the combination of advanced quantum mechanical treatments and stochastic modelling of relaxation processes.
