Semiclassical Approach to Photophysics Beyond Kasha’s Rule and Vibronic Spectroscopy Beyond the Condon Approximation. The Case of Azulene

Jacques-Edouard Moser, Jiri Vanicek, Zhan Tong Zhang, Antonio Prlj, Tomas Zimmermann, Tomislav Begusic, George Cameron Fish, Seonghoon Choi, Marius Wehrle, Julien Roulet

Azulene is a prototypical molecule with ananomalousfluorescence from the second excited electronic state,thus violating Kasha’s rule, and with an emission spectrum thatcannot be understood within the Condon approximation. To betterunderstand the photophysi ...

Shapes of rotating normal fluid He-3 versus superfluid He-4 droplets in molecular beams

Christoph Bostedt, Andre Al Haddad

Previous single-pulse extreme ultraviolet and x-ray coherent diffraction studies revealed that superfluid He-4 droplets obtained in a free jet expansion acquire sizable angular momentum, resulting in significant centrifugal distortion. Similar experiments ...

Parallel gas spectroscopy using mid-infrared supercontinuum from a single Si3N4 waveguide

Tobias Kippenberg, Camille Sophie Brès, Davide Grassani, Clemens Herkommer, Eirini Tagkoudi

Efficient third-order nonlinear optical processes have been successfully integrated on silicon nitride (Si3N4) waveguides. In particular, owing to Si3N4 wide transparency window spanning from the visible to the middle-infrared (mid-IR), efficient mid-IR di ...

Unimolecular fragmentation and radiative cooling of isolated PAH ions: A quantitative study

Eduardo Carrascosa Casado

Time-resolved spontaneous and laser-induced unimolecular fragmentation of perylene cations (C20H12+) has been measured on timescales up to 2 s in a cryogenic electrostatic ion beam storage ring. We elaborate a quantitative model, which includes fragmentati ...

Nanophotonic supercontinuum-based mid-infrared dual-comb spectroscopy

Luc Thévenaz, Tobias Kippenberg, Camille Sophie Brès, Junqiu Liu, Hairun Guo, Wenle Weng, Wolfgang Hänsel

High resolution and fast detection of molecular vibrational absorption is important for organic synthesis, pharmaceutical processes, and environmental monitoring, and is enabled by mid-infrared (mid-IR) laser frequency combs via dual-comb spectroscopy. Her ...

Molecular Platform for Frequency Upconversion at the Single-Photon Level

Tobias Kippenberg, Christophe Marcel Georges Galland

Direct detection of single photons at wavelengths beyond 2 mu m under ambient conditions remains an outstanding technological challenge. One promising approach is frequency upconversion into the visible (VIS) or near-infrared (NIR) domain, where single-pho ...

The instrument suite of the European Spallation Source

Henrik Moodysson Rønnow, Markus Strobl, Michael Müller, Paul Gregory Freeman, Ursula Bengaard Hansen

An overview is provided of the 15 neutron beam instruments making up the initial instrument suite of the European Spallation Source (ESS), and being made available to the neutron user community. The ESS neutron source consists of a high-power accelerator a ...

Using SLIM-Based IMS-IMS Together with Cryogenic Infrared Spectroscopy for Glycan Analysis

Thomas Rizzo, Ahmed Ben Faleh, Stephan Warnke, Priyanka Bansal, Ali H Abikhodr, Vasyl Yatsyna, Natalia Yalovenko

The isomeric heterogeneity of glycans poses a great challenge for their analysis. While combining ion mobility spectrometry (IMS) with tandem mass spectrometry is a powerful means for identifying and characterizing glycans, it has difficulty distinguishing ...
