The bark of the roots of Piscidia carthagenensis afforded the known insecticides rotenone (1) and millettone (2), as well as the new rotenoid piscicartone (3). The structure of 3 followed from nuclear magnetic resonance studies, while its absolute configuration (AC) was determined by vibrational circular dichroism (VCD) measurements in comparison with discrete Fourier transform B3LYP/DGDZVPcalculated spectra using the Compare VOA software. In addition, the AC of 1 and 2 was verified using the same VCD methodology.

Abstract95Mo Fourier transform nuclear magnetic resonance studies were made on aqueous solutions of oxo thiomolybdates. Chemical shifts up to 2200 ppm were found for the different unambiguously assigned species MoO4-nSn2- (n = 0, 1, 2, 3, 4).

125Te nmr spectra of a number of organotellurium compounds and inorganic tellurium salts are reported. The tellurium shielding has been found to be dependent upon the nature and number of electronegative substituents bonded to tellurium and where applicable, upon the para substituents on the phenyl ring. Possible reasons for the observed broad line widths are discussed.
