Abstract

Recent development of experimental microwave spectroscopy1 and ab
initio oomputational techniques based on Gaussian atomic funciti0!!1:S 2 have
made aV'ailable values of diamagnetic susceptibilities and individual second moments of the electronic charge distributtons for a large IIlUmber of molecules.
The analysis of the experimental results have led Blickensderfer et al.3 to the development of empirical rules for the .out-of plane < c2 > second moments for plranar molecules involving first row atoms and hydrogens. These empirical rules were later rationalized within the zer.o-differential .overlap approximation at the CND0/2 level of sophi:stica1tion4• Subse.quently, iit was shown that simrilar additivi·ty rules hold for in plane second moments < a2 >
and < b2 > 1f .they are calculated fiirst
