Xk. Jiang et al., FIRST SUCCESSFUL CORRELATION OF THE UV SPECTRA OF 3 KINDS OF STYRENESWITH SPIN-DELOCALIZATION SUBSTITUENT CONSTANTS SIGMA(CENTER-DOT), Journal of physical organic chemistry, 8(3), 1995, pp. 143-148
UV spectra of 17 paro-Y-snbstituted styrenes, 8 para Y-substituted alp
ha-methylstyrenes and 20 para-Y-substituted alpha,beta,beta-trifluoros
tyrenes were measured and correlated against spin-delocalization subst
ituent constants (sigma) with confidence levels above 99.9%.
