RELATIONSHIP BETWEEN THE WORKING QUALITY OF ASTURIAN JETS (SPAIN) AND THEIR STRUCTURE USING PARAMETERS DEFINED BY 1H‐NMR*

A collection of seven representative jets from Asturias (Spain) was studied. Some artisans of the Asturian jet industry established the quality criteria of the jet based on the user‐friendly properties of this material. In this work, we study the relationship between the working quality of asturian jets and their structure using parameters defined by liquid ¹H‐NMR. With this aim, certain parameters calculated from the NMR results were used to provide information about the structure of compounds extracted from jets.
