Publisher Summary This chapter reviews the syntheses and reactions of 6-membered
heterocyclic ring systems, such as diazines and benzo derivatives. The diazines pyridazine …

The formation and destruction mechanisms of interstellar dust analogs formed from a variety
of polycyclic aromatic hydrocarbon (PAH) and hydrocarbon molecular precursors are …

The dissociative double photoionization of isoxazole molecules has been investigated
experimentally and theoretically. The experiment has been carried out in the 27.5–36 eV …

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 …

Photofragmentation of thymine and 5-bromouracil into cation and neutral fragments
following the core ionization by soft x-rays using photoelectron-photoion-photoion …

The electron impact mass spectroscopy and the total ion collection measurements were
used to investigate the ionization and ionic fragmentation of the pyrimidine, C 4 H 4 N 2 …

In the present work, we studied the photoinduced ion chemistry of the halogenated
pyrimidines, a class of prototype radiosensitizing molecules, in the energy region 9–15 eV …

Formation of the excited CN (B 2 Σ+) free radicals in the photodissociation of pyridine (C 5 H
5 N) and pyrimidine (C 4 H 4 N 2) molecules was investigated over the energy ranges 16 …

The pyridine molecule has been examined by the means of photoelectron and threshold
photoelectron spectroscopies. Ionization energies were determined for both outer and inner …
