Quadrupole Splittings in Liquid Crystals,ge quadrupole moments which couple with inhomogeneous electric fields. In those cases considered so far it has been tacitly implied that the molecular environment is isotropic, . that all directions of the electric field gradient with respect to the external magnetic field are equally probable.

Postulate

Halide Ions in Biological Systems,h a protein, another macromolecule or some other molecule of biological interest. The efficiency of the quadrupolar relaxation mechanism for liganded halogen nuclei in a non-symmetric environment (cf. Chapter 2) results in clearly observable changes in the transverse and longitudinal relaxation time

Deduct

Studies of the Perchlorate Ion,ents have been made. The perchlorate ion (as also the perbromate and periodate ions) does, however, not fit well into this scheme for the present treatment: The chlorine atom is participating in covalent bonds but the field of applications is more closely related to that of halide ions. Since the Cl

Introductory Aspects,n the halogen (X.). . Equally well known are covalent halogen compounds with bonds of the type R-X. In fact with the exception of helium, neon and argon all elements in the Periodic Table can form halogen compounds of some kind.

Halide Ions in Biological Systems,s even when only a very small fraction of the ions become liganded. This effect, which has been termed “chemical amplification”, forms the basis of studies of biological problems through Cl, Br and I NMR.

Multiple

Studies of the Perchlorate Ion, NMR properties of the perchlorate ion are in some important respects rather different from those of both covalent organic compounds and halide ions, it was found most convenient to discuss these studies separately.
