The review focusses on the fundamental importance of non-covalent interactions in nature by illustrating specific examples from chemistry, physics and the biosciences. Laser spectroscopic methods and both ab initio and molecular modelling procedures used for the study of non-covalent interactions in molecular clusters are briefly outlined. The role of structure and geometry, stabilization energy, potential and free energy surfaces for molecular clusters is extensively discussed in the light of the most advanced ab initio computational results for the CCSD(T) method, extrapolated to the CBS limit. The most important types of non-covalent complexes are classified and several small and medium size non-covalent systems, including H-bonded and improper H-bonded complexes, nucleic acid base pairs, and peptides and proteins are discussed with some detail. Finally, we evaluate the interpretation of experimental results in comparison with state of the art theoretical models: this is illustrated for phenol...Ar, the benzene dimer and nucleic acid base pairs. A review with 270 references.

“…Thanks to the continual improvement of its resolution resulting from the exploitation of electric field ionization sequences, 15,24,25 PFI-ZEKE photoelectron spectroscopy, initially applied to resolve the rotational structure in the photoelectron spectra of diatomic molecules, has rapidly been applied to obtain information on the rovibrational photoionization of more com- ethene, 31,32 and allene. 33 The present results on propene illustrate the possibility of partially resolving the rotational structure in single-photon photoelectron spectra of structurally more complex molecules.…”

The pulsed-field-ionization zero-kinetic-energy photoelectron spectra of the origin band of the X ˜+ 2 A′′ r X 1A′ transition of propene (C 3 H 6 ) and perdeuterated propene (C 3 D 6 ) have been recorded at high resolution, allowing for the partial resolution of the rotational structure. The analysis of the spectra in the realm of the orbital ionization model for rigid-rotor asymmetric-top molecules enabled the determination of the adiabatic ionization energy of propene and the rotational constants of C 3 H 6 + and C 3 D 6 +. The tunneling splittings resulting from the hindered rotation of the methyl group could not be resolved, and the analysis was therefore carried out in the C s molecular symmetry group. Angular momentum contributions of p π , d π , and d δ character were included in the single-center expansion describing the molecular orbital out of which ionization occurs, leading to the selection rules |∆N| ) |N + -N′′| e 2 and ∆K a ) K a + -K a ′′ ) (1, (2 and to photoelectron partial waves with angular momentum quantum number up to l ) 3. The observation of a strong spectral feature associated with ∆K a ) 0 indicates the importance of vibronic interactions. † Part of the "Klaus Mu ¨ller-Dethlefs Festschrift".

“…The Rydberg-based gates are also one time and irreversible because the molecule is destroyed. These problems can be avoided by making use of the already demonstrated experimental ability to slice the ZEKE spectrum by the application of a stepwise ionizing field (18,19) (34) so as to break the ᐉ and m quantum numbers or to delay the second frequency with respect to the first. Time-resolved ZEKE spectroscopy (35) revealed that there is more than one time scale in the dynamics of high Rydberg states.…”

Connected logic gates can be operated on the levels of one molecule by making use of the special properties of high Rydberg states. Explicit experimental results for the NO molecule are provided as an example. A number of other options, including that of several gates concatenated so as to operate as a full adder, are discussed. Specific properties of high Rydberg states that are used are: their autoionization is delayed so that they can be distinguished from direct multiphoton ionization, during their long life such states also can decay by energy transfer to the molecular core in a way that can be controlled by the judicious application of very weak external electrical fields, and the Rydberg states can be detected by the application of an ionizing electrical field. The combination of two (or three) color photons with and without external weak fields allows the construction of quite elaborate logic circuit diagrams and shows that taking advantage of the different intramolecular dynamics of levels that differ by their excitation enables the compounding of logic operations on one molecular frame. molecular computing ͉ concatenated circuits ͉ zero electron kinetic energy spectroscopy T he dynamics of high molecular Rydberg states, of principal quantum number n of 100 or more, has received much recent interest (1-6). The essential findings that are relevant to this paper are mentioned briefly in the abstract and are summarized further below. The studies of the dynamics were motivated both by the applications to ZEKE (zero electron kinetic energy) spectroscopy and by the inherent interest in the unusual dynamical regime exhibited by such states (7). We show here how this new understanding and the technological capabilities developed for these experiments allow a novel type of application: the concatenation of several logic gates by using only one molecular frame (8).Computing with molecules is becoming an active area of research. Single-molecule-based rectifiers (9) and switches (10, 11) have been reported recently and offer a quite different approach (12) to molecule-based computing. The switches can be turned on or off by both redox and chemical inputs (13). The switch allows an electrical current to flow or not by causing a conformational change in [2]catanane-type molecules.
