The application of computers in the determination of the transformation parameters of the l-transformation has raised questions with regard to the accuracy of this procedure. In graphical methods, the accuracy of emulsion calibration is at least partially checked visually, but computer procedures require the inclusion of specific tests for this purpose. The accuracy of the determination of the transformation parameters depends primarily on the experimental procedure used in the evaluation and also, to some extent, on the state (age) of the emulsion used. 相似文献

The nitrosylcarbonylisonitrile complexes η5-C5H5M(NO)(CO)CNR (R = Me for Cr, Mo, W; R = Et, SiMe3, GeMe3, SnMe3 for Mo) are formed by treatment of the nitrosylcarbonylcyanometalates Na[η5-C5H5M(NO)(CO)CN] with [R3O]BF4 (R = Me, Et), Me3SiCl, Me3GeCl or Me3SnCl. The isoelectronic dicarbonylisonitrile compounds η5-C5H5Mn(CO)2CNR (R = SiMe3, GeMe3, SnMe3, PPh2, AsMe2) and η5-C5H5Re(CO)2CNAsMe2 are obtained by analogous reactions of Na[η5-C5H5M(CO)2CN] (M = Mn, Re) with Me3ECl (E = Si, Ge, Sn), Ph2PCl and Me2AsBr.With phosgene the anionic complexes Na[η5-C5H5M(CO)2CN] (M = Mn, Re) can be transformed into the new carbonyldiisocyanide-bridged dinuclear complexes η5-C5H5M(CO)2CN-C(O)-NC(OC)2M-η5-C5H5. Finally, the reactions of η5-C5H5M(NO)(CO)CNMe (M = Cr, Mo, W) with NOPF6, leading to the cationic dinitrosylisonitrile complexes [η5-C5H5M(NO)2CNMe]+, are described. 相似文献
