Abstract

Coriolis-induced vibrational mixing in S₁ H₂CO near E′_vib=2000-2300 cm^-1 is manifested by the rotational quantum number (J′,K′_a) dependent variation of the emission intensity in the rotationally resolved, dispersed fluorescence spectrum. The c-axis Coriolis resonance between 2¹4³ (K′_a=5) and 2¹4¹6¹ (K′_a=4) is observed with ξ_st ^(c)≃0.2 cm^-1. The b-axis Coriolis interaction between 2¹4¹6¹ (K′_a=5) and 4 ⁴6¹ (K′_a=4) in S₁ as well as the a-axis Coriolis interaction between 4₂ and 4₁6 ₁ in S₀ are observed. A significant degree of vibrational mixing is observed in the energy range, E′_vib=2000-2300 cm ^-1.
