The ground electronic state of the C3Kr van der Waals complex has been studied by the wavelength-resolved emission from the à state. The vibrational levels of the C3Kr complex have been compared with those of the C3Ar to ensure the spectral assignments of these two complexes.The perturbation of the C3 bending vibration (both in-plane and out-of-plane bending motion) by the rare gas atom has been observed; the vibrational amplitude of the C3 bending motion of the complex becomes more restricted than the monomer.
