Electronic absorption spectra of benzoquinone and its hydroxy substituents and effect of solvents on their spectra.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 56(5) , 965-81, (2000) The electronic absorption spectra of 1,4-benzoquinone (BQ) and its 2,5-dihydroxy and tetrahydroxy derivatives have been studied in detail. The interpretation of the electronic bands is made on the basis of PPP and CNDO calculations. It is found that the pi --... |

Inelastic neutron scattering (INS) studies on 2,5-dihydroxy-1,4-benzoquinone (DHBQ).
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 59(3) , 537-42, (2003) Inelastic neutron scattering (INS) spectra of solid 2,5-dihydroxy-1,4-benzoquinone were measured and compared with IR and Raman data. The INS spectrum is very well reproduced in the region below 1000 cm(-1) by DFT calculations on the B3LYP/6-311++G** level us... |

Comparison of conventional and synchrotron X-ray structure determinations of the adduct 1,2,4,5-tetrahydroxybenzene-2,5-dihydroxy-1,4-benzoquinone (1/1) and a conventional X-ray structure determination of 1,2,4,5-tetrahydroxybenzene monohydrate.
Acta Crystallogr. C 57(Pt 6) , 730-4, (2001) The X-ray structure of 1,2,4,5-tetrahydroxybenzene (benzene-1,2,4,5-tetrol) monohydrate, C6H6O4*H2O, (I), reveals columns of 1,2,4,5-tetrahydroxybenzene parallel to the b axis that are separated by 3.364 (12) and 3.453 (11) A. Molecules in adjacent columns ar... |
