Oscillations in Water Solutions of Mixture Polyaminoacids and Tempo Spin Probe Irradiated by Near Infrared

  • Chapter
Spectroscopy of Biological Molecules

Abstract

Near infrared absorption (NIR) has been known to activate proton transfer in molecular crystals containing hydrogen bonds [1]. In presented experiments, the same process is observed in water solution of L-glutamic and poly-L-glutamic sodium salt in presence of spin probe TEMPO — a free radical.
