Femtolysis – Investigation of biological relevant molecules by femtosecond lasers coupled to a FT-ICR mass spectrometer — •Christian Neidel¹, Andreas Kühn², Frank Noack¹, Claus Peter Schulz¹, Ingolf V. Hertel¹, and Michael Linscheid² — ¹Max Born Institute, Max-Born-Str. 2a, 12489 Berlin — ²Department of Chemistry, Humboldt-Universität zu Berlin, Brook-Taylor-Str. 2, 12489 Berlin

First experiment on the combination of Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer with intense femtosecond laser pulses will be reported. By means of the strong laser field fragmention and sequencing of large biomolecules like DNA and proteins was introduced and detected with high mass resolution provided by this type of mass spectrometer. Results for several different molecular model systems will be presented. These type of experiments provide a new approach to study protein sequencing and fragmentation of, e.g., messenger molecules and pollutants.
