We have prepared and characterized a few Mn (III) complexes by using a few bidentate and tridentate ligands. Spectra of the manganese (Abstract We have prepared and characterized a few Mn (III) complexes by using a few bidentate and tridentate ligands. Spectra of the manganese (III) ion in a variety of molecular environments are reported . On the basis of solution spectra, some of these co...

The authors apply a cryogenic ion-beam storage ring in order to measure the intrinsic lifetime of metastable a${}^{1}$$\mathrm{\ensuremath{\Delta}}$ state CH${}^{\ensuremath{-}}$ molecular ion.

the charge-transfer complexation reaction between iodine and dibenzo- 18-crown- 6 (db18c6) has been studied spectrophotometrically in chloroform solution at different temperatures. the resulting donor-acceptor complex was formulated as (db 18c6…i )i . the spectrophotometric results , as well as the conductivity measurements, indicated that the gradual release of tiiodide ion from its contact io...
