Nuclear Spin Relaxation in Liquids and Gases

The aim of this report is to cover the progress of work in the field of magnetic relaxation and self-diffusion in liquids and gases over a period of twelve months from June 2000 to May 2001, and is a continuation of the report given last year.  

As in previous periods, this review is limited to work on comparatively simple liquids and solutions of physico-chemical and chemical interest, as publications in the field of macromolecules and biological chemistry are covered elsewhere in this volume. Of course, such a distinction is sometimes problematic, as innovative work dealing with solutions of complex molecules may be of interest for research in the field covered here. Thus, at the risk of duplication, some interesting studies dealing with more complex systems are mentioned briefly. 

At the beginning of this chapter it is convenient to quote some authoritative reviews in the subject area. More specialized reviews will be discussed in the corresponding subsections. Also, some important general trends are briefly highlighted here. Details will be discussed later in this chapter.

The research activity in the field of supercritical fluids is increasing steadily since the end of the 1980s. There are several reasons for the increasing interest in supercritical fluids. First, new technical processes were developed. Reaction kinetics can be strongly effected in the supercritical region by varying temperature and pressure. Second, the supercritical state presents the intermediate state between the liquid and the gas phase. Physicochemical properties 

Reinhardt reviewed the development of NMR for solving structure and dynamics of molecular systems. In particular he focused on the contributions of the first chemist working in the field of NMR, Herbert S. Gutowsky. 

During the past two years, significant advances have been made in the development of NMR methods for studying biomolecular dynamics on the microsecond to millisecond timescale. Thuduppathy and HilP reviewed applications of NMR spin relaxation methods for measuring biological motions. Fernandez and Wider discussed transverse relaxation-optimized spectroscopy (TROSY) that promises to further enhance the determination of solution structures of large biomolecules.

In line with its predecessors. Volume 39 of the SPR on NMR aims to provide a comprehensive coverage of the NMR literature. The relevant hterature is that appearing between June 2008 and May 2009. Unfortunately the reporter for the Chapter on Nuclear Spin Relaxation in Liquids and Gases was unable to fulfil his commission for this Volume. Thus it is intended to include a report covering two years of work in this area in Volume 40.
