Proline is a unique amino-acid, with a secondary amine fixed within a pyrrolidine ring
providing specific structural properties to proline-rich biopolymers. Gas-phase proline …

An experimental photochemistry study involving gas-and solid-phase amino acids (glycine,
DL-valine, DL-proline) and nucleobases (adenine and uracil) under soft X-rays was …

The valence photoelectron spectra of the aromatic amino acids phenylalanine, tyrosine,
tryptophan and 3-methylindole in the gas phase have been investigated by soft X-ray …

The photofragmentation spectra of guanine, cytosine, leucine and methionine were
measured with noble gas resonance radiation at energies from 8.43 to 21.2 eV, and the …

Photoionization techniques, such as photoelectron spectroscopy (PES) and photoionization
mass spectrometry (PIMS), are well-established and powerful methods for studying the …

Absolute total non-dissociative and partial dissociative cross sections of pyrimidine were
measured for electron impact energies ranging from 70 to 400 eV and for proton impact …

The aliphatic amino acids glycine, valine, leucine, and isoleucine are thermally placed into
the gas phase and expanded into a vacuum system for access by time of flight mass …

We present results on the valence level excitation, ionization and dissociation of adenine,
using time‐of‐flight mass spectrometry and synchrotron radiation, in the vacuum ultraviolet …

We report on the current status and performance of the toroidal grating monochromator
