Photoassociation spectroscopy of ultra-cold long-range molecules

Comptes Rendus. Physique, 2004
Spectroscopic study of so-called long-range molecules, with average interatomic distances much larger than usual for chemical bonds, is conveniently performed by photoassociation (PA) of ultracold atoms. We present here a review of our results obtained by one and two-photon PA spectroscopy of the Cs2 molecule, using as intermediate the 0g− and 1u ...

Coherent multidimensional spectroscopy of dilute gas-phase nanosystems

Nature Communications, 2018
Coherent multidimensional spectroscopy has greatly advanced our understanding of molecular dynamics but was so far broadly limited to complex condensed phase probes. Bruder et al.

Accretion and photodesorption of CO ice as a function of the incident angle of deposition [PDF]

, 2019
Non-thermal desorption of inter- and circum-stellar ice mantles on dust grains, in particular ultraviolet photon-induced desorption, has gained importance in recent years.

H2 formation via non-Born-Oppenheimer hydrogen migration in photoionized ethane

Nature Communications, 2023
Neutral H2 formation via intramolecular hydrogen migration in hydrocarbon molecules plays a vital role in many chemical and biological processes. Here, employing cold target recoil ion momentum spectroscopy (COLTRIMS) and pump-probe technique, we find ...
