A tilted pulse-front setup for femtosecond extreme ultraviolet transient grating spectroscopy in highly non-collinear geometries
A. Battistoni, H. A. Dürr, M. Gühr +1
We demonstrate a tilted pulse-front transient grating technique that allows to optimally utilize time-resolution as well as transient grating line density while probing under grazi…

Probing ultrafast ππ*/nπ* internal conversion in organic chromophores via K-edge resonant absorption
T. J. A. Wolf, R. H. Myhre, J. P. Cryan +21
Organic chromophores with heteroatoms possess an important excited state relaxation channel from an optically allowed ππ* to a dark nπ*state. We exploit the element and site specif…

Signature of a polyamorphic transition in the THz spectrum of vitreous GeO2
Alessandro Cunsolo, Yan Li, Chaminda N. Kodituwakku +10
The THz spectrum of density fluctuations, , of vitreous GeO at ambient temperature was measured by inelastic x-ray scattering from ambient pressure up to pressures wel…
