First results are presented obtained with an experimental setup developed to record IR spectra of rotationally state-selected ions. The method we use is a state-selective version of a method developed by Schlemmer et al. [Int. J. Mass Spectrom. 185, 589 (1999); J. Chem. Phys. 117, 2068 (2002)] to record IR spectra of ions. Ions are produced in specific rotational levels using mass-analyzed-threshold-ionization spectroscopy. The state-selected ions generated by pulsed-field ionization of Rydberg…

Formation of ultracold ion pairs through long-range Rydberg molecules
We propose a new approach to excite ion-pair states of ultracold dimers. The central idea is a two-step process where first long-range Rydberg molecules are formed by photoassociation, which are then


A Novel Method to Measure Electronic Spectra of Cold Molecular Ions
A universal method has been developed for measuring spectra of molecular ions in a 22-pole radio frequency trap at 5 K. It is based on laser induced inhibition of complex growth (LIICG). The first

The spectroscopic study of molecular cations in the gas phase poses a range of challenges which are generally associated with their high chemical reactivity, the difficulties in producing
Laser induced reactions in a 22-pole ion trap: C2H2++hν3+H2→C2H3++H
A sensitive experimental method for ion spectroscopy and state specific reaction dynamics is described, briefly called laser induced reactions (LIR). The technique is based on (i) trapping ions over
Infrared spectroscopy to probe structure and dynamics in metal ion-molecule complexes
Vibrational spectroscopy measurements are described for mass-selected metal cation-molecular complexes using the technique of infrared resonance-enhanced photodissociation (REPD) spectroscopy. We
Preparation of ions in selected rotational states by delayed pulsed field ionization
A novel method of preparing ions in selected rovibronic states is presented. It is based on pulsed field ionization of long‐lived high‐n Rydberg states lying just below the different rovibronic
Based on the method to confine charged particles in inhomogeneous radiofrequency fields, two experimental set-ups have been developed for the study of ion–molecule reactions approximating
High-precision and high-accuracy rovibrational spectroscopy of molecular ions.
A versatile new instrument capable of measuring rovibrational transition frequencies of molecular ions with sub-MHz accuracy and precision is presented, expected to open up many new possibilities for state-of-the-art ab initio calculations and astronomical observations.
High-resolution Photoelectron Spectroscopy
The evolution of photoelectron spectroscopy of neutral molecules in the gas phase, from its first applications in the early 1960s to the present day, is reviewed with emphasis on the description of
