    Description / Table of Contents: The mass spectra of dimethyl phosphonates (I to X) derived from norbornane, norbornene and nortricyclene have been studied. The fragmentation of endo and exo isomers is quite similar (only the peak intensities vary a little) except for the saturated compounds I and II where the orientation of the P(O)(OCH3)2 group seems to exert an influence. The spectra of the norbornene derivatives III and IV and of the isomeric nortricyclic compound IX are quite different. The fragmentation pattern of all phosphonates I to X is dominated by the localisation of the charge on the phosphorus moiety.
    Notes: Les spectres de rnasse de phosphonates diméthyliques (I à X) dérivés du norbornane, du norbornène et du nortricyclane ont été étudiés. La fragmentation des isoméres endo et exo est trés comparable (seules les intensités des pics varient légèrement) sauf pour les dérivés saturés I et II où l'orientation du groupe P(O)(OCH3)2 inhence les coupures. Les spectres des dérivés du norbornène III et IV et du composé nortricyclique isomère IX sont très différents. La fragmentation des phosphonates I à X est dominée par la localisation de la charge sur le fragment phosphoré.
