Radical nitroxide, its manufacturing process and its application in magnetometry and gyrometry. The nitroxide radical of the invention has the following formula I or II: (CF DRAWING IN BOPI) in which R1 and R2 are independently chosen from alkyl, alkoxyl, dialkylaminyl, phenyl, optionally deuterated, H, D or Cl radicals; R3, R8 and R9 are independently chosen from alkyl, alkoxyl, phenyl and optionally deuterated radicals; R4, R5, R6, R7 are independently chosen from alkyl, alkoxyl, dialkylaminyl, phenyl, optionally deuterated, COOH, OH, OD, H, D, halogen, COOR (where R is an alkyl radical); R1 0 and R1 1 are independently selected from alkyl, alkoxyl, dialkylaminyl, phenyl, optionally deuterated, COOH, OH, OD, H, D, a halogen, COOR (where R is an alkyl radical), or represent an atom of oxygen linked to the radical ring by a double bond. |
