Synthesis and properties of some spin labeled long chain aliphatic acids

Article abstract of DOI:10.1139/v82-105

We have synthesized and characterized a series of spin labeled aliphatic acids with variable chain lengths between the nitroxide radicals and the carboxylic group.These molecules should be of general utility in labeling a variety of substrates wich can react with the free carboxylic group.Variable temperature esr studies have been conducted with some of these molecules to characterize molecular motion as a function of solvent viscosity.
