“…For example, only one conformer of 1-indanol has been detected by microwave experiments [85] whereas more have been seen in REMPI or LIF measurements. [86,87] Last, the microwave spectra become rapidly intractable when the size of the molecule increases, which explains that microwave spectroscopy has been limited to small systems.…”

Noncovalent interactions are particularly intriguing when they involve chiral molecules, because the interactions change in a subtle way upon replacing one of the partners by its mirror image. The resulting phenomena involving chirality recognition are relevant in the biosphere, in organic synthesis, and in polymer design. They may be classified according to the permanent or transient chirality of the interacting partners, leading to chirality discrimination, chirality induction, and chirality synchronization processes. For small molecules, high-level quantum chemical calculations for such processes are feasible. To provide reliable connections between theory and experiment, such phenomena are best studied in vacuum isolation at low temperature, using rotational, vibrational, electronic, and photoionization spectroscopy. We review these techniques and the results which have become available in recent years, with special emphasis on dimers of permanently chiral molecules and on the influence of conformational flexibility. Analogies between the microscopic mechanisms and macroscopic phenomena and between intra- and intermolecular cases are drawn.

“…Important results have been obtained by resonanttwo-photon-ionization (R2PI) excitation spectra of the S 1 S 0 transition of mass resolved hydrogen bonded molecular complexes [1][2][3][4][5][6]. To observe the electronic transitions of chiral systems -typically their fluorescence spectrum -this technique requires a chromophoric group.…”

“…The spectra are complicated by vibronic transitions associated with the many conformers of the adducts. As already observed for other chiral clusters, both [I R · X R ] and [I R · X S ] complexes exhibit spectral signatures characterized by a significant red shift ∆ν of the 0 0 0 S 1 ← S 0 transition relative to that of the bare chromophore I R [12]. The spectral shifts reflect the combined effect of the electrostatic and dispersive interactions between C and solv on the HOMO and LUMO energies of the chromophore.…”

Abstract.A laser spectroscopic and mass spectrometric study of ionic and molecular clusters of biological interest is reported. The molecules of interest and their aggregates were generated in a supersonic beam and analyzed by mass resolved resonant two photon absorption and ionization (R2PI) and by collision induced mass spectrometry (CID-MS). The absence of the solvent allows to study these systems in the isolated state free of undesired solvent effects which may level off the differences in their properties. The gas phase results have been compared to theoretical estimates of the structure and stability of the systems under investigation.
