Abstract
The free jet millimeter wave spectrum of the pyridazine-argon molecula r complex has been investigated in the 60-75 GI-Iz frequency range, Fr om the information contained in the rotational spectrum the equilibriu m position of the argon atom with respect to the center of mass of pyr idazine (x(e) = -0.368, y(e) = 0.0 and z(e) = 3.427 Angstrom, respecti vely) and the two bending and stretching force constants (f(xx) = 0.21 1, f(yy) = 0.214, f(xx) = 2,052, N m(-1), respectively) have been obta ined.
