Mass-Analyzed-Threshold-Ionization-Spectroscopy of Pyrazine and Pyrazine-Ar
Zeitschrift für Physikalische Chemie, 2007Vibrational spectra of the pyrazine and the pyrazine-Ar cation in the electronic ground state (D 0) have been measured via several intermediate states of the first excited state (S 1) by mass-analyzed threshold ionization spectroscopy.

Experiments on the synthesis of pyrazine nucleosides
Journal of the Chemical Society, Perkin Transactions 1, 1975Pyrazine nucleosides were prepared by condensation of acylglycosyl halides with trimethylsilyloxypyrazines in benzene in the presence of silver perchlorate. Reaction of 2,3,4,6-tetra-O-acetyl-α-D-glucopyranosyl bromide (1) with 2,3-bis(trimethylsilyloxy)pyrazine (2) gave 1,4-dihydro-1,4-bis-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl) pyrazine-2,3-dione

Quantum dynamics of the photostability of pyrazine
Physical Chemistry Chemical Physics, 2015We propose a new mechanism for the radiationless decay of photoexcited pyrazine to its ground electronic state involving a conical intersection between the dark Au(nπ) state and the ground state.

The pyrazine-binding protein and olfaction
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19881. The present results provide circumstantial evidence, but not a proof, that the Pyrazine-binding Protein is an odorant carrier molecule of fundamental importance. 2. At first sight a role for a secretory protein in olfaction is not obvious. 3.
