H2XP:OH2 Complexes: Hydrogen vs. Pnicogen Bonds
Crystals, 2016 A search of the Cambridge Structural Database (CSD) was carried out for phosphine-water and arsine-water complexes in which water is either the proton donor in hydrogen-bonded complexes, or the electron-pair donor in pnicogen-bonded complexes.

Do Hydrogen Bonds Influence Excitonic Splittings?
CHIMIA, 2016 The excitonic splitting and vibronic quenching of the inversion-symmetric homodimers of benzonitrile, (BN)2, and meta-cyanophenol, (mCP)2, are investigated by two-color resonant two-photon ionization spectroscopy.
