MOLESs – MOlecular Excited State spectroscopy
is an international initiative born from the need to modernize and expand the classic series by Melvin Robin on higher excited states of polyatomic molecules. The project will assemble authoritative and complete data on the excited states of molecules (valence and Rydberg). We will present their experimental absorption spectra (VUV, EUV and PES) and compare experiment with theoretical derivations of excitation energies and spectra. Data will be published in both e-book format and on-line with recommended data sets.
