Understanding how nuclear motions affect vibrational motions in molecular liquids remains challenging in modern condensed matter physics. Here the authors study the vibrational quantum effects in liquid water and show the sensitivity on the coherent

In theoretical simulations of a UV + x-ray pump-probe (UVX-PP) setup, we show that frequency detuning of the pump UV pulse acts as a camera shutter by regulating the duration of the UVX-PP process. This two-photon absorption with long overlapping UV

Publikováno v: The Journal of Chemical Physics. 158:114304

We study the rotational dynamics induced by the recoil effect in diatomic molecules using time-resolved two-color x-ray pump-probe spectroscopy. A short pump x-ray pulse ionizes a valence electron inducing the molecular rotational wave packet, wherea

Ultrafast dissociation of ammonia: Auger Doppler effect and redistribution of the internal energy

We study vibrationally-resolved resonant Auger (RAS) spectra of ammonia recorded in coincidence with the NH2+ fragment, which is produced in the course of dissociation either in the core-excited 1s−14a11 intermediate state or the first spectator 3a

Significance Water is the matrix of life and behaves anomalously in many of its properties. Since Wilhelm Conrad Röntgen, two distinct separate phases have been argued to coexist in ambient water, competing with the alternative view of the single-ph
