The 1H and 13C NMR resonances of 19 tetracyclic acridinone derivatives were completely and unambiguously assigned by a combination of 1H-detected one-bond HMQC and long-range (two and three bonds) HMBC correlation experiments. 1H and 13C chemical shifts are also reported for the respective N -aryl b

The 1H and 13C NMR resonances of four 3H-naphtho[2,1-b]pyrans were completely and unambiguously assigned by a combination of homonuclear (gs-COSY), 1H-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradient-selected correlation experiments.

The complete assignment of the 1H and 13C NMR spectra of eight thienyl-substituted chromenes was achieved by the concerted application of homonuclear (gs-COSY), 1H-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradientselected correlation experiments.
