Avance 3 nmr spectrophotometer

The complex, bismuth(III) tris(N-methyl-N-phenyldithiocarbamate), was characterized using Alpha Bruker FTIR spectrophotometer for the identification of functional groups. Elementar, Vario EL Cube for the analysis of the percentage C, H, N, and S, and a Bruker Avance III NMR spectrophotometer (600 MHz) for the (¹H and ¹³C) NMR measurement in chloroform. The as-synthesized nanostructures were characterized by X-ray diffraction using a Bruker AXS D₈ Discover XRD (Cu K˛ = 1.5406A) X-ray diffractometer operated at 40 KV and 40 mA. The UV-vis-NIR absorption spectra of the nanostructures solutions were measured in toluene using a Perkin Elmer Lambda 750S UV-vis-NIR spectrophotometer. A JEOL JEM 2100 High Resolution Transmission Electron Microscope (HRTEM) was used for TEM imaging. This was done at an accelerating voltage of 200 kV. Spatula tips of samples were dispersed in ethanol and sonicated for 30 min and allowed to dry for a few minutes prior to analysis. Scanning electron microscope (SEM) analysis was carried out using a FEI Quanta FEG 250 Environmental Scanning electron microscope (ESEM), and the elemental composition was determined using Oxford X-map 20 detector at 15 kV and using INCA software for energy dispersive X-ray analysis (EDAX).
