Xuv Postionization of Fragments of Photodissociated (260"
نویسنده
چکیده
We report experimental evidence for the loss of neutral C, C2, C3, and C4 from photoexcited c60 and C70. These species are detected by postionization with XUV radiation formed by four-wave mixing in Kr vapor. The fragments have been detected in the nascent distribution (i.e., before total disintegration of the fullerene-size molecular entities). A resonant autoionization transition in C atom has yielded an upper limit to the translational energy release for dissociation into C atoms. The detection of these products gives new insight into the fragmentation mechanism of fullerenes.

Background: Molecular DNA markers are one of the most important tools in molecular biology labs. The size of DNA molecules is determined by comparing them with known bands of markers during gel electrophoresis. There are many different protocols to produce these kinds of molecular markers. In this study we have suggested an efficient strategy to produce molecular weight markers in industrial pr...
متن کاملEffects of orbital symmetries in dissociative ionization of molecules by few-cycle laser pulses
We have measured angular distributions of ion fragments produced in dissociative double ionization of CO, CO2, and C2H2 by intense ultrashort laser pulses. This report extends similar recent studies of O2 and N2 to a wider set of molecules. We found that for sub-10-fs pulses of sufficiently low intensity the fragments’ angular distributions for all studied molecules are determined by angular de...
متن کامل157 nm photodissociation of a complete set of dipeptide ions containing C-terminal arginine.
Twenty singly-charged dipeptide ions with C-terminal arginine were photodissociated with 157 nm light and their tandem mass spectra recorded. Many of the small product ions that were observed are standard peptide fragments that have been commonly seen in VUV photodissociation studies. However, the study of a library of dipeptides containing all 20 N-terminal amino acids enabled the recognition ...
متن کاملImaging with ion beams and laser postionization.
We investigate the use of a liquid metal ion gun (LMIG) combined with multiphoton resonance ionization of sputtered atoms and/or molecules to acquire mass-selected images with submicrometer spatial resolution. Images from several model systems are presented including those of an In grid, and of patterned surfaces of benzo[a]pyrene and tryptophan thin films. Since postionization for these system...
متن کاملLaser desorption postionization mass spectrometry of antibiotic-treated bacterial biofilms using tunable vacuum ultraviolet radiation.
Laser desorption postionization mass spectrometry (LDPI-MS) with 8.0-12.5 eV vacuum ultraviolet synchrotron radiation is used to single photon ionize antibiotics and extracellular neutrals that are laser desorbed both from neat and intact bacterial biofilms. Neat antibiotics are optimally detected using 10.5 eV LDPI-MS but can be ionized using 8.0 eV radiation, in agreement with prior work usin...
