Resonant raman scattering of vibrationally highly excited supersonic-jet-cooled SO2 molecules

The resonant Raman scattering spectra of vibrationally highly excited SO molecules with the vibrational energy of ∼3.7×10 cm exhibit relatively wide (∼50 cm) structurized bands. This spectral width is attributed to the mixing of vibrational levels of the ground electronic state due to a non-adiabatic interaction with the vibrational levels of the electronically excited state .
