MPcules already contains diverse atomic, molecular, and reaction properties. In the future, we aim to expand the properties available, both to aid in chemical analysis and to enable the development of ML methods. In particular, we are interested in expanding properties in two directions: spectroscopy and electronic densities. At present, the only spectra included in MPcules are IR spectra obtained via vibrational analysis. With modest modifications to our existing workflows, we should be able to additionally obtain molecular Raman spectra, including Raman activities and intensities. We also intend to incorporate nuclear magnetic resonance (NMR) spectra, including chemical shifts and J-couplings. In terms of charge densities, NBO provides detailed information regarding atomic and hybrid orbitals but does not describe the spatial extent of such orbitals or the total charge density around atoms in a molecule. Inspired by the recently developed charge density dataset included in the Materials Project, we intend to present total molecular charge densities to MPcules users via the Materials Project API and web site, as well as information regarding the electron densities of individual molecular orbitals.
