Understanding the molecular interactions responsible for chiral recognition is
of primary importance in life chemistry. Gas-phase experiments on either
neutral or ionic adducts of chiral molecules allow for the study of intrinsic
properties of chiral recognition in solvent-free conditions. With contributions
from a panel of international experts exploring a variety of subjects, Chiral
Recognition in the Gas Phase describes the structural and energetic aspects of
The first part of the book focuses on optical spectroscopy in jet-cooled
conditions in neutral chiral molecules and complexes. The spectroscopic methods
range from microwave, IR, and UV spectroscopy to circular dichroism effects in
photoelectron spectroscopy. The book also discusses issues related to the
homochirality of life.
The second section describes mass spectrometry approaches to chiral
recognition in ionic complexes. These approaches encompass the study of the
stability of supramolecular chiral host-guest adducts, the study of chiral
catalysts and chiral selectors, the use of small DNA sequences as auxiliaries
for discriminating the enantiomers of amino-acids, and the probe of the
chirality of a single amino acid within a peptide chain.
Chiral recognition on a molecular level is essential for the rational design
of chiral separation media and for understanding the fundamental interactions
between biological molecules. It is especially important in all of the life
chemistries, particularly in pharmacology, due to the differences in behavior
between the enantiomers of a chiral molecule embedded in a chiral surrounding.
This volume cogently and comprehensively describes the state-of-the-art work
that has been devoted to understanding of the forces at play in chiral
