✦ Synopsis
From the ENDOR spectra of the mononegative ions of biphenyl and ortho-, meta-and para-terphenyl in solution complete sets of hyperfiie splitting constants could be determined. The splittings are interpreted in terms of SCJ! MO spin densities obtained from McLachlan tyDe calculations It turns out that n-u soin dekxalization effects do not play a significant role in the spin density distribution in ably from coplanarity.
