INTRODUCTION

In recent years a number of first principles or ab initio quantum mechanical

methods have been developed which allow the accurate calculation of NMR shielding

constant tensors for large molecules and for molecular models of solids. In addition to

more efficient implementations of the conventional common-origin coupled Hartree-Fock perturbation theory and finite perturbation theory methods which were applied to small

molecules in the 1960's, new methods have been developed based upon localized

molecular orbitals and methods employing so-called gauge-including atomic orbitals

have been improved. It has also become feasible to go beyound the Hartree-Fock level,

including the effects of electron correlation using many body perturbation theory,

polarization propagator techniques or multi-configuration SCF approachs. Greater

understanding of the basis set dependence of the calculated shieldings has also improved

their accuracy and reliability and has allowed their extension both to larger molecules

and to many different types of magnetic nuclei, including transition metals and heavy

main-group elements. As a result of these improvements in methodology, coupled with

dramatic increases in the speed and storage capacity of routinely available computers, it

has now become possible for many groups, using many different methods, to accurately

calculate NMR shielding constant tensors for fairly complicated molecules.

The status of the various methods was reviewed at this workshop, and it was

agreed that the results obtained with the various localized orbital and gauge including

orbital methods were quite similar. The gauge-including atomic orbital method seems to

have slightly superior accuracy if very small basis sets are used, but all the localized and

gauge-including methods seem to converge to the same result using larger bases.

Common-origin methods with core electron corrections can also give reasonably good

absolute shieldings, but are perhaps best used for small molecules (for which very large

basis sets can be employed and core corrections are small) or, when applied to large

molecules, for analysis of shielding trends (rather than absolute shieldings) and in the

elucidation of the electronic mechanisms of the shielding and the relationship between

the shielding and other electronic properties. Studies of correlation effects using the

various methods show many cases in which such effects seem fairly small, but also some

(e.g. compounds with both multiple bonds and lone pairs and compounds poorly

described by a single determinant wavefunction) in which they seem quite large. There is

not yet sufficient experience with such correlation effects to make possible a simple, reliable estimation of their magnitudes in all cases.

Substantial advances have also recently occurred in experimental NMR

spectroscopy, with improved methhods for detennining the orientations of NMR

shielding tensors in liquids and solids, with the use of many-dimensional NMR

techniques to uniquesly assign resonances to structural sites and with studies of changes

in the shielding tensor with changes of temperaute, phase or crystal structure. Some new

NMR techniques uniquely relevant to the determination of the relationship between the

shielding tensor and the geometric structure were reviewed in the workshop. Changes in

shielding constants with changes in local geometry were also reviewed for minerals,

glasses, semiconductors and for the compounds of many main group and transition

elements. In many cases, predominantly experimental talks also incorporated first

principles calculations to help in the assignment of shieldings to sites and in the

determination of shielding tensor orientations. These calculations provided rigorous tests

for the efficiency and accuracy of these methods when applied to large molecules.

In addition to the discussions of ftrst principles calculations, there were several

presentations stressing the utility of qualitative molecular orbital or semiempirical

analyses of shielding trends. Some connections were made between these approachs and

those based on frrst principles calculations, and the validity of some of the semiempirical

approachs was discussed. The importance of validating the assumptions of the

semiempirical approachs by appeal to fust principles calculation or other electronic

structural data was stressed, but it was concluded that such approachs still had great

value for systematizing shielding constant data, interpolating high precision values of

shielding constants from strucural data and identifying correlations for futher study by

frrst principles methods.

Overall, the conclusion of the workshop was that present and emerging methods,

along with expected computational advances, would make possible calculations at post­

Hartree-Fock accuracy on quite large molecules in the near future. It was not so clear

exactly how these capabilites could best be used to update and improve the present non­

specialist's understanding of NMR shielding constants or to deepen our overall

understanding of molecular electronic strcture. These remain important general topics for

future discussion.

The Organizing Committe for the workshop consisted of:T. D. Bouman (Southern

Illinois Univ. at Edwardsville, USA, deceased); P. Lazzeretti (Univ. of Modena, Italy); G.

E. Maciel (Cororado State Univ., USA); J. A. Tossell (Univ. of Maryland, USA); and G.

A. Webb (Univ. of Surrey, UK). Generous ftnancial support was provided by the NATO

Scientiftc Affairs Division. Additional support was provided by Biosym Technologies,

To give more of the flavor of the workshop the papers are presented in the order given,

with the names of the lecturers marked with an asterix. Informal discussions were also

held on the topics: (1) "How does the compound in the computer relate to that in the

NMR spectrometer?", (2) "Do other electronic properties correlate with NMR

shieldings?", and (3) "How do correlation and relativity affect NMR shieldings?". A

review of the methods used for shielding constant calculations and an evaluation of their

accuracy is given by G. A. Webb in the fIrst chapter, entitled "An Overview of Nuclear

Shielding Calculations" and a brief summary of the meeting lectures and discussions,

along with some suggestions for future research, is given by C. J. Jameson in the fInal

chapter, entitled "Overview and Directions for the Future". Also included are one-page

abstracts of most of the posters presented at the workshop.
