DESCRIPTION:Speaker: Edit Mátyus\nhosted by Laszlo Erdös\nAbstract: High-
 resolution spectroscopy experiments provide us information about the inter
 nal motion of molecular systems with an extraordinary detail and precision
 . Aiming at a quantitative agreement with the experimental data makes it n
 ecessary to massively extend our knowledge about the fundamental propertie
 s of molecular matter. In this talk\, I will report on recent progress alo
 ng challenging directions of this field. Multiple\, coupled\, large-amplit
 ude motions in high-dimensional quantum systems are ubiquitous in nature\,
  still quantitative solution of the corresponding Schrdinger equation is e
 xtremely challenging. I will point on the main bottlenecks and explain our
  solution strategy. Coupling in the quantum mechanical motion of the elect
 rons and the atomic nuclei in molecules is thought to be understood by and
  large. When it comes to a quantitative understanding\, even the smallest 
 molecular systems\, H2 and H3+\, turn out to be extraordinarily difficult.
  I will speak about a perturbative and a variational approach to the elect
 ron-nucleus problem. For certain energetic and structural ranges\, the com
 putations could have been carried out with full rigor\, and we are in a po
 sition to assess relativistic\, quantum electrodynamics\, and finite-nucle
 ar size effects in molecules to be compared with the experimental data.
