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.
