Cold Molecules: Preparation, Applications, and Challenges
Angewandte Chemie International Edition, 2009AbstractResearch with cold molecules has developed rapidly in recent years. There is now a variety of established methods for cooling molecules into the millikelvin range. Nevertheless, a focal point of current research is directed toward finding new ways to bring the temperature of molecules even closer to absolute zero.

Cold collisions of hot molecules
Physical Chemistry Chemical Physics, 2023Stimulated emission pumping is combined with imaging to study inelastic collisions of highly vibrationally excited NO down to 2 K. Results are compared to quantum close-coupling calculations on high-level potential energy surfaces.

SPIE Proceedings, 2002
An experiment is described in which 10 8 CaH molecules have been confined in a magnetic trap at a temperature of 400 mK. The elastic scattering cross section of CaH on 3 He was measured to be σ el equals(1.5±0.6)×10 -14 cm 2 . A lower bound of Γ rotational g10 -15 cm 3 s -1 was placed on the rotational elastic collision rate coefficient, and an ...

Why are Cold Molecules so Hot?
ChemPhysChem, 2009AbstractBrrrr! Cold molecule and cold atom research are juxtaposed and the challenges in cooling and trapping molecules are recounted. Both indirect and direct techniques of producing cold and slow molecules (such as buffer‐gas cooling and magnetic trapping, see picture) are described.

Science, 2019
Cold Molecules Arrays of optical tweezers have been used to trap atoms, but trapping and laser-cooling molecules in this setting is tricky. Such an approach would, however, be generalizable to many molecular species. Anderegg et al. created an optical tweezer array of calcium monofluoride molecules, which were laser cooled to their ground state (see ...

Cold Collisions of Electrons with Molecules
Few-Body Systems, 2002Results are presented of high-resolution scattering experiments involving electron collisions with CO2 and CS2, between a few meV and 200 meV impact energy. Virtual state scattering is shown to dominate the low-energy behaviour for both species. The most striking features of the scattering spectrum for CS2 are, however, giant resonances with cross ...

Heteronuclear cold molecules laser spectroscopy
Summaries of Papers Presented at the Quantum Electronics and Laser Science Conference, 2003Summary form only given. In order to characterize the K-Cs sample we performed trap loss measurements to evaluate the heteronuclear losses introduced by the overlapped samples one to each other. We present the heteronuclear loss rate observed on a cesium magneto-optical trap (MOT) due to collisions with the cold potassium atoms as a function of the Cs ...
