J Mol Model . 2013 Apr; 19(8):3095-102. PMID: 23605138
Dipole moments (μ), charge distributions, and static electronic first-order hyperpolarizabilities (β(μ)) of the two lowest-energy keto tautomers of guanine (7H and 9H) were determined in the gas phase using Hartree-Fock,...

Alparone A, Librando V
Spectrochim Acta A Mol Biomol Spectrosc . 2012 Sep; 98:479-80. PMID: 22981589
The title paper [1] incorrectly establishes that, in gas phase the global minimum energy structure of 1-nitronaphthalene is planar (C(s) symmetry). By contrast, present calculations indicate that the planar C(s)...
