  2. A lot of organic quantum chemical calculations admit intuitively such a consideration without giving a precise definition to the concept of reaction pathway

  10. 3N-6 is even true for linear structures (ifN is greater than 2) in order to provide a continuous description between linear and nonlinear nuclear configurations
  11. E.g. for three-atomic systems the internal set of coordinates (R 1 R 2 R 3) produces for linear structure a discontinuity due to the constraintR 3=R 1+R 2; such a set is not convenient in order to avoid the problem of kinks

  13. In general the chain rule may be written as: (?y f) = (?yx?)(?x f)

  17. The expression ofG. Matrix is:G =B?B', whereB connects the cartesian displacements, ?, to the internal displacements,s:s=B? and where ? stands for the matrix of the inverse of the atomic masses
