The idea that molecules repel each other at small separations while attracting each other at
long range was developed in the second half of the 19th century and first stated clearly by …

The extremely improved resolution of ZEKE spectroscopy is one of its main advantages over
conventional photoelectron (PE) spectroscopy. A good illustration of this is provided by the …

We investigate recently published methods for extending density functional theory to the
description of long-range dispersive interactions. In all schemes an empirical correction …

The review focusses on the fundamental importance of non-covalent interactions in nature
by illustrating specific examples from chemistry, physics and the biosciences. Laser …

Since 1984, ZEKE (ZEro Kinetic Energy) spectroscopy has matured into a very high
resolution spectroscopy for the study of cations, anions, and indirectly through these …

General rovibronic symmetry selection rules, which are applicable to any molecular
symmetry, have been obtained for the photoionization of polyatomic molecules. The use of …

The absolute photoabsorption, photoionisation and photodissociation cross-sections and
the photoionisation quantum efficiency of benzene and hexadeuterobenzene have been …

In a high resolution uv-uv double resonance experiment with two Fourier-transform limited
nanosecond laser pulses high Rydberg states up to n> 100 were selectively excited and …

We give a detailed characterization of a recently developed method to prepare
translationally cold, internally state-selected molecular ions in ion traps [X. Tong, AH …

Infrared spectra of phenol− X (X= C6H6, C2H4, and C2H2) clusters in the neutral and
cationic ground states were observed in the OH stretching vibrational region. For the neutral …
