The methanol-to-hydrocarbons (MTH) process involves the conversion of methanol, a C1 feedstock that can be produced from green sources, into hydrocarbons using shape-selective microporous acidic catalysts – zeolite and zeotypes. This reaction yield

Ultrafast Photo-Ion Probing of the Relaxation Dynamics in 2-Thiouracil

Autor: Matthew Scott Robinson, Mario Niebuhr, Markus Gühr

Publikováno v: Molecules, Vol 28, Iss 5, p 2354 (2023)

In this work, we investigate the relaxation processes of 2-thiouracil after UV photoexcitation to the S2 state through the use of ultrafast, single-colour, pump-probe UV/UV spectroscopy. We place focus on investigating the appearance and subsequent d

The VUV photoionisation and photofragmentation of cyclo-alanine-alanine (cAA) has been studied in a joint experimental and theoretical work. The photoelectron spectrum and the photoelectronphotoion coincidence (PEPICO) measurements, which enable cont
