The new interpretation of physical phenomenon in EPR spectra of fluoroalkyl n-radicals was made. We named this phenomenon the relay charge effect of fluorine hyperfine coupling (RCE-F). The sharp relationship of Fermi contact spin density on 19F nucleus and the radical charge was found out. The orbital origin of current effect was investigated.ΠΠΏΠ΅ΡΠ²ΡΠ΅ ΠΎΠΏΠΈΡΠ°Π½ΠΎ ΠΈ ΡΠ΅ΠΎΡΠ΅ΡΠΈΡΠ΅ΡΠΊΠΈ ΠΏΡΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡΠΎΠ²Π°Π½ΠΎ Π½Π°Π±Π»ΡΠ΄Π°Π΅ΠΌΠΎΠ΅ Π² ΡΠΏΠ΅ΠΊΡΡΠ°Ρ

Fermi contact couplings in fluoroalkylsubstituted -radicals. Relay charge effect of luΠΌΠΎ and homo and its quantum chemical modeling by means of indo calculations
