2H Isotope Effect on 13C Chemical Shifts of Nitro-Benzo-9-Crown-3
Deuterium substitution on two ortho-substituted-OCH2-fragments in Nitro-Benzo-9-Crown-3 induces low frequency shifts, positive mnDCj, in all 13C NMR resonances which is an indication of the increased shielding in this crown ether. The magnitude of these shifts vary from 15DC7=716 to 54DC3=15 ppb for...
