Query: Ro-Vibrational Hamiltonian of Three Body Systems Near Collinear
  Configurations   Recent developments on three body systems have revealed that dynamics of
trajectories passing through collinear configurations can be easily adopted. We
analyse the reduction procedure in order to detect the points where collinear
configurations are deviating. Then we show that the value of the reduced
Hamiltonian can be computed at these points.
