Ma. Vincent et al., ELECTRON CORRELATION AND THE STRUCTURE OF 1-HYDROTRIOXY AND 2-HYDROTRIOXY - AN AB-INITIO AND DENSITY-FUNCTIONAL APPROACH, Chemical physics letters, 233(1-2), 1995, pp. 111-114
The predicted structures of the 1- and 2-hydrotrioxy radical are simil
ar at the Brueckner doubles and density functional (B-LYP) levels of t
heory, but differ from those found using ab initio methods employing a
lower level of electron correlation.
