Infrared spectroscopy of mass-selected gas-phase ions
 |
Mass spectrometry can determine the molecular weight with high accuracy, however, the molecular structure often remains elusive. IR spectroscopy yields detailed information about the molecular structure, but standard methods are unable to obtain gas-phase ion spectra. Here we use FELIX to obtain action spectra of mass-selected ions to determine their structure. Jos Oomens / Jeff Steill |
Infrared absorption spectroscopy of jet-cooled (bio-)molecules
 |
IR/UV double resonance laser techniques are applied to obtain conformer selective spectra jet-cooled biomolecules, such as amino acids, peptides, sugars, as well as model systems for molecular motors. A new molecular beam machine has just been commisioned. Anouk Rijs / Sander Jaeqx / Jos Oomens |
Infrared absorbtion spectroscopy of ions of astrophysical interest
 |
Infrared spectra of ionized polycyclic aromatic hydrocarbons (PAHs) and related species in the gas phase are investigated. These spectra are studied in view of the hypothesized occurrence of these species in the interstellar medium. Hector Alvaro Galue / Jos Oomens |
Metal cluster dynamics
 |
Investigation of infrared spectra of all kinds of pure metal, metal-carbide, metal-oxide, and metal-nitride clusters, in order to obtain structural information. These studies bear relevance to current problems in heterogeneous catalysis as well as astrophysics of the inter- and circumstellar medium. Vivike Lapoutre/ Joost Bakker |
