Abstract

Using solid-state13C NMR spectroscopy and also measurements of proton spin-lattice relaxation times T 1 and second moments M 2 , we have investigated molecular motion in solid inclusion compounds of deoxycholic acid with ferrocene in the interval 100–400 K. We have identified various dynamic processes occurring with participation of molecules of the matrix and the included molecules. We have shown that in addition to rapid reorientations of the cyclopentadienyl rings, the ferrocene molecules undergo 180° jumps about the C 2 axis. We have determined the parameters for all the molecular motions. We discuss the conformational state of the included molecules.
