✦ Synopsis

Note that Becke actually uses the correlation functional for the uniform electron gas parametrized by Perdew and Wang [ 1 ] in place of the VWN one and a more recent gradient-correction due to the same authors [ 21. These changes have, however, only negligible consequences.

The TZVP basis set used in the computations is not the 6-3 lG( d, p) set as mentioned on page 433, but the 6-31 lG(d, p) set.

A recently introduced density functional incorporating gradient corrections and some Hartree-Fock exchange has been used to study the isomerixation of formaldehyde radical cation to its distonic form. Both direct and water-assisted mechanisms have been considered. Structural and energetic quantities
