Free Jet Absorption Millimeter Wave Spectrum and van der Waals Potential Energy Surface of the Pyridazine−Argon Adduct
The free jet millimeter wave spectrum of the pyridazine−argon molecular complex has been investigated in the 60−78 GHz frequency range. From the information contained in the rotational spectrum the equilibrium position of the argon atom with respect to the center of mass of pyridazine (x e = −0.368,...

| Zusammenfassung: | The free jet millimeter wave spectrum of the pyridazine−argon molecular complex has been investigated in the 60−78 GHz frequency range. From the information contained in the rotational spectrum the equilibrium position of the argon atom with respect to the center of mass of pyridazine (x e = −0.368, y e = 0.0 and z e = 3.427 Å, respectively) and the two bending and stretching force constants (f xx = 0.211, f yy = 0.214, f xx = 2.052 N m-1, respectively) have been obtained. |
