Non-covalent interactions

We published in Chemistry: A European Journal a Minireview on rotational studies of non-covalent interactions, which appeared in the Reviews Showcase section of the Journal. In the article, entitled “The Hydrogen Bond and Beyond: Perspectives for Rotational Investigations of Non‐Covalent Interactions“, we emphasize how the new broadband microwave techniques have boosted the possibilities for analyzing larger clusters and weaker interactions with rotational resolution.

The forest of non-covalent interactions has more trees than expected. Read the minireview to check out why.

Coherent rotational dynamics

Category : General News

The group of Prof. Jochen Küpper at DESY & Uni. Hamburg have reported in Nature Communications the observation of the laser-induced rotational dynamics of OCS, or, in simple words, a “movie” of OCS rotating in the ps-scale time. In this experiment a rotational wavepacket is created on a molecular beam of OCS using two laser pulses. The beam is later probed with a third laser.

A word of caution: Remember that molecular rotation is different to the rotation of a macroscopic stick, as microscopic objects are described by quantum mechanics.

Summer conferences

Category : Conferences , Group News , Talks

Our group participated in several conferences this Summer. Marcos Juanes attended the 74 International Symposium on Molecular Spectroscopy (ISMS) at the University of Illinois last June 17-21, presenting three oral talks. Alberto Lesarri gave oral talks at the 18 European Symposium on Gas-Phase Electron Diffraction (ESGED18) in Hirschegg (Austria), the Iberian Joint Meeting on Atomic and Molecular Physics (IBER2019) in Évora (Portugal) and the XXXVII Biannual Meeting of the Spanish Physics Society (Bienal Física 2019) in Zaragoza (Spain).

The IBER2019 conference is the biannual meeting of the Portuguese (SPF) and Spanish (RSEF) Physics Society. The event is coorganized by the SPF and the Division of Atomic and Molecular Physics (GEFAM) of the RSEF. This year the event remembered the GEFAM founder Prof. Gerardo Delgado-Barrio (CSIC), who passed away in 2018.
