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
