PREFACE
The holding of the 8th Jerusalem Symposium was saddened by the sudden death of
Professor Ernst D. Bergmann at the very eve of this meeting. With him disappeared
one of the leading world scientists in the field of physical chemistry and biochemistry.
His innumerable friends and admirers over the whole world mourn him profoundly.
All those who knew him personally and among them the participants in the previous
Jerusalem Symposia will remember for ever the exceptional qualities of the scientist
and the unusual human warmth of the man.
With Ernst D. Bergmann the state of Israel lost one of the founders of its Science
and one of its most brilliant and renowned representatives. The spirit which he suc
ceeded to inoculate into his numerous disciples and pupils will, however, continue to
perpetuate his name and his work. The Jerusalem Symposia will continue as a living
testimony to his brilliant inspiration.
Before dying, Professor Bergmann has prepared a few opening remarks for the
8th Jerusalem Symposium. They are reproduced here.

OPENING WORDS
Prepared by the Late Professor Ernst David Bergmann
It gives me great pleasure to welcome you all on behalf of the President and the Rector
of the Hebrew University which is co-sponsoring this meeting, and of the President
and Council of the Israel Academy of Sciences and Humanities which for the eighth
time has put its premises at our disposal.
If we look at the central subject to which these symposia have been devoted we can
see a clear progress towards more and more complex problems, trying each time to
memorize what we know and to formulate the questions which remain open. This is
the first time that we deliberately leave the consideration of individual molecules and
try to assemble our knowledge of the effect of the surroundings on the individual
molecules.
Jerusalem is a unique city - there is none other like it. Many of you, perhaps most
of you, may have expected this symposium to take place in a warlike atmosphere.
It is true the country is at war, but you wiII see it is not militarized. This is true for the
country as a whole. We are ready to fight for our survival as a State but we are not
wiIIing to give up the normal pursuit of development generally and particularly in
the sciences.
We are grateful to the Baron Edmond de Rothschild and the Israel Academy of
Sciences and Humanities for the possibility to show our friends this phenomenon
which, in my opinion, is a good omen for the future, and I hope that you wiII enjoy
the serene and quiet atmosphere of this country, of this city and of this bUilding.
MOLECULAR ORBITAL 'SUPERMOLECULE'
APPROACH TO THE SOLVATION PROBLEM

1. Introduction
Until very recently, the theoretical evaluation of the effect of the medium on the
behavior and properties of molecules was beyond the reach of quantum mechanical
computations, essentially due to the prohibitive size of the systems which would have
to be considered. Thus the habit evolved to treat essentially the isolated molecule and
be satisfied by qualitative considerations or, at best, approximate evaluations of the
bulk effect of the medium following early models [1]-[3]' The last few years have seen
a number of attempts at a refinement of these 'continuum' or 'macroscopic' represen
tations [4, 5, 6, 7]. One constant and essential inconvenience of these models is, how
ever, the absence of precision concerning the arrangement of the solvation layer(s)
around the solute, which is considered as residing in a cavity (generally spherical)
embedded in a polarizable dielectric. No information is obtainable in this way about
the details of the short-range solute-medium interactions.
Recently, a different line of research started to be developed which consists of a
'discrete' treatment, in which one tries to establish the individual effect of the medium
molecule(s) upon the system studies. This is achieved in general through the utiliza
tion of the 'supermolecule' model which combines, in a unique exploration, the molec
ular entities in interaction, such as the solute and the solvent molecule(s). Such an
approach became possible owing to the very recent considerable developments in the
applicability of the molecular orbital method: it is now possible to compute non
empirically a system solute + solvent of reasonable size, treating all the electrons in the
field of all the nuclei. In this fashion one may evaluate the most probable sites of
interaction and gather information about the nature of the binding, if any, the binding
energy and also the flexibility of the association.
This second way of approach is obviously particularly well adapted for dealing with
the problem of 'bound' water in a broad sense. Its particular aim is the detection of
the preferred, if such, modes of interaction of the solvent molecules with the receptor
and the characterization of such interactions. The second stage of the research consists
in determining the extent to which this primary interaction produces observable and
measurable effects.
We have applied this approach in our laboratory to the exploration of the hydration
scheme of a series of fundamental biological molecules, and in particular of the con
stituents of the biological polymers and related systems: formamide [8], N-methyla
cetamide [9], the hydrogen-bonded peptide linkages of proteins [10, 11], the amino
