Antiferromagnetic ordering in van der Waals 2D magnetic material MnPS 3 probed by Raman spectroscopy

One-Dimensional van der Waals Material Tellurium: Raman Spectroscopy under Strain and Magneto-Transport.

Experimental demonstrations of one-dimensional (1D) van der Waals material tellurium (Te) have been presented by Raman spectroscopy under strain and magneto-transport. Raman spectroscopy measurements have been performed under strains along different principle axes. Pronounced strain response along the c-axis is observed due to the strong intrachain covalent bonds, while no strain response is ob...

Constraining Van der Waals quintessence by observations

We discuss an alternative approach to quintessence modifying the usual equation of state of the cosmological fluid in order to see if going further than the approximation of perfect fluid allows to better reproduce the available data. We consider a cosmological model comprising only two fluids, namely baryons (modelled as dust) and dark matter with a Van der Waals equation of state. First, the ...

Spectroscopy on triphenylamine and its van der Waals complexes

Both vibrationally and rotationally resolved spectra of the S, + So transition in jet-cooled triphenylamine (TPA) around 340320 nm are reported. Medium resolutton spectra (0.5-l .O cm-’ resolution) are recorded using ( 1 + 1 )-resonance enhanced multi photon iomzation (REMPI) with mass selective time-of-flight (TOF) detection in a pulsed molecular beam apparatus. The origin ofthe S,+ So transit...

Rovibronic spectroscopy of the van der Waals complex He–HClþ

The potential energy surfaces and the calculated rovibronic spectrum of the electronic ground state of the van der Waals He–HClþ cation are presented. The system is in a X electronic state at linearity, which splits into an A0 and an A00 state upon bending, leading to a Renner– Teller effect. Three-dimensional potential energy surfaces have been determined using the partially spin-restricted op...
