Abstrakt

The generation of organic particle beams is studied in combination with

photoionization using uv radiation at 266 nm and vuv light at 157 nm.

Single-photon ionization with pulsed vuv light turns out to be sensitive enough

to detect various large neutral biomolecular complexes ranging from metal-amino

acid complexes to nucleotide clusters and aggregates of polypeptides. Different

biomolecular clusters are shown to exhibit rather specific binding

characteristics with regard to the various metals that are co-desorbed in the

source. We also find that the ion signal of gramicidin can be increased by a

factor of fifteen when the photon energy is increased from 4.66 eV to 7.9 eV.
