摘要：

The 4J(H-C=C-Me) coupling constant, previously established1-3 as a probe of bond order, was used to examine the bond orders in a series of ortho-bridged compounds:, benzocyclopropene, 1, 2-dihydrobenzocyclobutene, indan and tetralin. No evidence for sterically induced bond fixation (i.e. the Mills-Nixon4effect) was found, but some evidence for electronic distortion in the corresponding benzyiic ketones was observed. The experimental results are in accord with SCF/MO calculations. © 1990 ASEG.
