Publikováno v: Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation IV.

We present the optomechanical design of the Potsdam Arrayed Waveguide Spectrograph (PAWS), which is the first on-sky demonstrator of an integrated photonic spectrograph specifically designed and optimized for astronomy. The instrument is based on an

Optical spectroscopy of isolated flavins: photodissociation of protonated lumichrome

Autor: Otto Dopfer, David Müller, Alexander Sheldrick, Alan Günther, Pablo Nieto

Publikováno v: Physical Chemistry Chemical Physics. 20:7407-7414

The optical properties of flavins strongly depend on the charge and oxidation states as well as the environment. Herein, the electronic spectrum of cold protonated lumichrome, the smallest flavin molecule, is recorded by means of photodissociation in

BerlinTrap: A new cryogenic 22-pole ion trap spectrometer

Autor: Pablo Nieto, Otto Dopfer, Alexander Sheldrick, David Müller, Dieter Gerlich, Alan Günther

Publikováno v: Journal of Molecular Spectroscopy. 332:8-15

The design and first applications of a new tandem mass spectrometer (BerlinTrap) combining an electrospray ion source, a quadrupole mass spectrometer, a cryogenic 22-pole ion trap (4–300 K), and an orthogonal reflectron time-of-flight mass spectrom

Effect of alkali ions on optical properties of flavins: vibronic spectra of cryogenic M+lumichrome ions (M = Li-Cs) in the gas phase

Autor: David Müller, Mitsuhiko Miyazaki, Alan Günther, Otto Dopfer, Pablo Nieto, Alexander Sheldrick

Publikováno v: Physical chemistry, chemical physics : PCCP. 20(No. 34)

The photochemical properties of flavins depend sensitively on their environment and are strongly modified by coordination with metal ions. Herein, the electronic spectra of cold complexes of the smallest flavin molecule (lumichrome, LC, C12N4O2H10) w
