As Kutzelnigg et al. pointed out, IGLO/DZ computed magnetic susceptibilities are generally larger than the experimental values. Moreover, there is often a range of experimental values in the literature due to errors, determinations with different methods, and measurements in gas, liquid, and solid states. Theoretical data have the advantage of uniformity and self-consistency. The errors tend to cancel in exaltation evaluations (A), which are not far from the values based on the experimental data. For example, the benzene A value, based on the equation 3(1,3-butadiene -ethylene) = benzene, is -14.5 (computed) and -14.8 (experimental). Dauben et al. (ref 22) gave -13.7 ppm cgs for benzene based on magnetic susceptibility increment systems using average values derived from many reference compounds, (e) For a summary of magnetic susceptibility data, see: Hellwege K.-H.; Hellwege, A.

    • 5 bond with the cyclopropyl ring, rather than to an error in assignment. Our MP2(fc)/6-31Gψ optimized C-C distances in substituted cyclopropanes, 1.508 Å in methyl cyclopropane, 1.510 Å in 1,2-cisdimethylcyclopropane, and 1.511 Å in 1,2,3-trimethylcyclopropane, show no significant hyperconjugation effects.
