Unirnolecular dissociation of Arz into Ari was investigated with a double focusing sector field mass spectrometer. Ar; was produced by electron impact ionization of Ar3 formed by nozzle expansion. It was found that the m&stable dissociation rate is strongly dependent on the sragnation gas temperatur

## Abstract The reversible __cis__/__trans__ photoisomerization of secondary thiopeptide bonds has been systematically studied with UVβvisible absorption, capillary electrophoresis, ^1^H NMR spectroscopy, and circular dichroism methods. It was found that the concentration of the __cis__ conformers
