Photoelectron spectroscopy of pyrazine anion clusters

摘要: We studied the energetics and character of electron binding in pyrazine anion clusters by mass spectrometry, photoelectron spectroscopy, theoretical calculations. The distribution showed that minimum number molecules a neat cluster to form an was two, with single molecule incapable accommodating excess electron. On other hand, even addition very weak solvent such as Ar sufficed bring affinity level below vacuum level. Photoelectron spectra some pyrazine-containing clusters, (Pz)1−–Arn (n=1–10) (Pz)1−–S1 (S=pyrazine, benzene, water), were obtained. A vibrational progression observed (Pz)1−–Arn. determined be −0.01±0.01 eV from extrapolation. small drop incremental (Pz)1−–Ar4 (Pz)1−–Ar5, indicating closure first solvation shell four atoms. dimer wa...
