Journal ArticleDOI
Femtosecond spectroscopy of condensed phases with chirped supercontinuum probing
TL;DR: In this article, a pump-supercontinuum-probe (PSCP) spectroscopy with femtosecond time resolution was developed theoretically and experimentally, and it was shown that the supercontinuum can be described as a single chirped pulse.
Journal ArticleDOI
Photoisomerization Dynamics and Pathways of trans- and cis-Azobenzene in Solution from Broadband Femtosecond Spectroscopies and Calculations
Martin Quick,A. L. Dobryakov,Mario Gerecke,Celin Richter,Falko Berndt,Ilya N. Ioffe,Alexander A. Granovsky,Rainer Mahrwald,Nikolaus P. Ernsting,Sergey A. Kovalenko +9 more
TL;DR: The photoisomerization of azobenzene in solution shows no viscosity dependence, putting into question the torsion mechanism and suggesting the hula-twist isomerization mechanism.
Journal ArticleDOI
Femtosecond pump/supercontinuum-probe spectroscopy: optimized setup and signal analysis for single-shot spectral referencing.
A. L. Dobryakov,Sergey A. Kovalenko,Alexander Weigel,J. L. Pérez-Lustres,J. Lange,A. Müller,Nikolaus P. Ernsting +6 more
TL;DR: A setup for pump/supercontinuum-probe spectroscopy is described which is optimized to cancel fluctuations of the probe light by single-shot referencing, and extends the probe range into the near-uv (1000-270 nm).
Journal ArticleDOI
Femtosecond Stimulated Raman Spectroscopy of Flavin after Optical Excitation
Alexander Weigel,A. L. Dobryakov,Bastian Klaumünzer,Mohsen Sajadi,Peter Saalfrank,Nikolaus P. Ernsting +5 more
TL;DR: The method is used here to characterize the excited-state properties of riboflavin and flavin adenine dinucleotide in polar solvents and to determine the resonance conditions for FSRS.
Journal ArticleDOI
Evidence for the phantom state in photoinduced cis–trans isomerization of stilbene
TL;DR: In this paper, the lifetime of p∗ is determined to be τ p ∗ = 0.4 ps in acetonitrile and 0.3 ps in hexane.
