There is considerable evidence that compounds in which a cyclopropane ring is located adjacent to an unsaturated linkage, such as a carbonyl group or double bond, exhibit many of the physical and chemical properties characteristic of substances conta

13C and 19F nuclear magnetic relaxation rates in liquid CFBr3 have been measured at 14.1 kG. By assuming that the motion of the molecules at low temperatures follows the classical diffusion model, the contributions of various relaxation mechanisms ha

An ESR study of the [RhCl6]4− center in single crystals of AgCl has been made. The g values and chlorine hyperfine interactions observed for the axial chlorines are consistent with a d7 configuration and localization of the odd electron largely in

The crystal structure of bromomalonamide, HBrC(CONH2)2, has been determined from MoKa diffractometer data by use of Patterson and Fourier syntheses. The crystals are orthorhombic, Pnma, with cell constants at 22°C: a =9.487(3) A, b =11.294(4) A, c =

Deuterium quadrupole coupling constants have been obtained for two symmetric‐top molecules in the liquid phase by combining NMR relaxation data with Raman line‐shape analysis of bands of A1 symmetry. The Raman lines have been corrected for vibrat

19F and 14N nuclear magnetic spin‐lattice relaxation rates in liquid CF3CN have been measured at 14.1 kG. From 14N relaxation rates, the correlation times of the tumbling motion were directly determined. By separating 19F relaxation rates into term
