The structure and inversIon bamer of PL13 has been studied using ab uutlo SCI-CI calculations The Inversion potential is very flat, showmg a mirumum at a bond angle of = 102" and a bamer of =2 2 kcal/mole. The effects of basis set on the calculated bamer are dscussed. \* Ref. [l] includes references

โฆ Synopsis
The barrier to inversion in NF$ has been studied using ab initio molecular-orbital theory including geometry optimization at the correlation energy level. The barrier is predicted to be 12.6 kcal mol-'. Comparison is made to previous theoretical and experimental results.
