## Abstract Proton dynamical polarization is a method which unites the advantages of continuous wave ESR sensitivity and pulsed NMR imaging in order to localize free radicals. Injected nitroxide has been imaged for the first time in living rats. The high sensitivity of this method to oxygen is demo

## Abstract By using the ESR and CIDNP methods the formation of free radicals in the reaction of nucleophilic and electrophilic substitution is proved. The role of free radicals in the mechanism of these reactions is discussed.
Rtived 22 March 19B5 Pulsed laser emission in &he red from Lhe short-kved radical p-aminophenylthiyl. generated phololyucally in organic sAution, is observed. Radicals are generated in their ground state and optically pumped in their excited skte. An apparent efficiency of =lS% is achieved
## Abstract Interactions between the diketopiperazine __cyclo__βalanylglycine and four fluorinated alcohols in waterβfluoroalcohol mixtures were examined by ^1^H{^19^F} intermolecular nuclear Overhauser effects (NOE) experiments. The alcohols studied were trifluoroethanol, hexafluoroacetone trihydr
