β¦ Synopsis
The tnverslon barner of AsF3 has been calculated usmg SCF theory wth a moderately large basu set of Slater type orbltals, mcIudmg poIarlzation functions on the central atom. The caIcu!ated barner is = 1 I2 kcal/mole. The highest occupied molecular orbnal m planar AsF3 IS shown to have A; symmetry, rather than A; symmetry typical for molecules of this type.
