    Notes: Summary In this paper we study a special case of vector fields, r-vector fields, which are defined in the same way as are the r-manifolds. It is then shown that for non-isotropic r-vecto-fields the1-form of recurrence is closed and for r 2 -vector fields the tensor of recurrence is symmetric and decomposable. Isotropic r-vector fields generate a local1-parameter group of difr feomorphisms or isometries if the covariant differential is skew-symmetric, and such that the orbit in each point is a geodesic.

    Description / Table of Contents: Three methods for obtaining solutions of Karplus-type equations and the calculation of errors are analysed. A geometric interpretation of the problem makes its solution by an iterative method possible.

    Description / Table of Contents: A method of best fitting for the calculation of vicinal coupling constants is presented for sp2-sp3 systems. Results for 68 vicinal coupling constants from 32 different products are presented. We obtain the best Karplus-type equation to date with a dispersion factor of 31,01%.
    Notes: On présente une tentative d'affinage de l'équation de Karplus pour des systèmes sp2-sp3. L'étude porte sur un total de 68 constantes de couplage vicinal venant de 32 produits différents. On obtient la meilleure équation de Karplus jusqu'à ce jour, avec un facteur d'accord relatif de 31,01%.
