Infrared spectroscopy combined with quantum chemical calculations indicates that the [ArB3O5]+, [ArB4O6]+ and [ArB5O7]+ cation complexes each involve an aromatic boroxol ring and an argon–boron covalent σ bond.

Fragmentation Patterns

A theoretical treatment is used to perform conformational studies of title compounds, which was previously successfully used within our group for characterization of fragmentation patterns of some bio-molecules. Now we present studies of electron impact ionization of 2 Furanmethanol, Tetrahydro (C5H10O2) and 3-Furanol, Tetrahydro (C4H8O2), both as important models for more complicated compounds like nucleic acids. In this paper geometry of the neutral and cationic conformers of these two molecules was optimized on the DFT level with B3LYP functional, and ionization energies were estimated. DFT calculated results are supplemented with G3MP2 calculations, and a set of higher-level ab initio methods were empirically corrected to obtain more reliable results.
