We describe the commissioning of a new electron–ion coincidence spectrometer used to diagnose the photon beam from a plane grating monochromator beamline at the ASTRID2 synchrotron radiation facility. The spectrometer allows determination of the ab

Publikováno v: Journal of the American Society for Mass Spectrometry

We employ cold ion spectroscopy (CIS) in conjunction with high-field asymmetric waveform ion mobility spectrometry (FAIMS) to study the peptide bradykinin in its doubly protonated charge state ([bk + 2 H](2+)). Using FAIMS, we partially separate the

Publikováno v: The Journal of chemical physics

In this work, we use laser-induced population transfer techniques to study the conformational isomerization of a helical peptide, Ac-Phe-(Ala)5-LysH(+), in a cold ion trap. In one scheme, called IR-UV hole-filling spectroscopy, a single conformation

Publikováno v: The Journal of chemical physics. 125(13)

We report the time-resolved recombination of photodissociated IBr-(CO2)n (n = 5-10) clusters following excitation to the dissociative IBr-A' 2Pi12 state of the chromophore via a 180 fs, 795 nm laser pulse. Dissociation from the A' state of the bare a

A new tandem mass spectrometer for photofragment spectroscopy of cold, gas-phase molecular ions

Autor: Thomas R. Rizzo, Oleg V. Boyarkin, Annette Svendsen, Ulrich J. Lorenz

We present here the design of a new tandem mass spectrometer that combines an electrospray ion source with a cryogenically cooled ion trap for spectroscopic studies of cold, gas-phase ions. The ability to generate large ions in the gas phase without
