## Abstract ^1^H NMR spectroscopy was used to determine the conformations of the aminoglycoside antibiotic __N__βdemethylclindamycin and two of its cyclic derivatives. The conformational features of these systems were determined by consideration of vicinal coupling constants and, in some cases, nuc

I3C and 'H NMR spectral data for a homologous series of tertiary arsines (R,As, where R = Me, Et, n-Pr and Ph), aminoarsines and arsonium and aminoarsonium salts are reported and discussed. In nearly all cases, quaternization of the tertiary arsine to its corresponding arsonium or aminoarsonium salt
H and lSC NMR chemical shifts are reported and assigned for 1,4,9,10-and 2,3,9,1 O-anthracenetetrone. In addition, NMR data are given for 2,3-dihydroxy-9, 1 O-anthraquinone, 2.3-dimethoxy-9.10anthraquinone and 1 -hydroxy-2-acetoxy-9,l O-anthraquinone, encountered during the preparation of the anthra
