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

Abstract
The ^1^H and ^13^C NMR chemical shifts of four 2,5‐diaryltetrahydrofuran derivatives and their dihydro precursors were assigned completely with certainty using a concerted application of one‐ and two‐dimensional experiments (DEPT, gs‐COSY, gs‐HMQC and gs‐HMBC) Copyright © 2006 John Wiley & Sons, Ltd.

## Reference Data and chemical shifts of some tetracyclic and 1H 13C pentacyclic acridinone derivatives
The 1 H and 13 C NMR chemical shifts of 16 4,5disubstituted acridine derivatives and nine 4-substituted-5,5 0 (˛0 0 ,ω 00diaminoacyl)bisacridine derivatives are reported. Chemical shift assignments were established from 1D and gradient-enhanced 2D measurements.
