Intermolecular Vibrations of the Complex of NO in the nsσ Rydberg States and Ar
The resonance enhanced multiphoton ionization method has been applied to the study of NO-Ar van der Waals complex in the nsσ (n = 3,4) Rydberg states. We have assigned the intermolecular vibrations appearing in the Ã— excitation spectrum of the complex. The bending structure appeared only with the excitation of the stretching mode in the Ã state, which was interpreted by intermolecular forces. The -Ã excitation spectra were independent of the initial intermolecular level in the Ã state and the dissociation threshold to NO(E2 ) + Ar was determined to be 60950 cm-1. The s–d mixing in the 4sσ orbital would make the intermolecular vibrational structure in the —Ãspectra complex.
