Abstract

Rovibrational states of the linear polyatomic acetylene molecule (C₂H₂) are not as simple as might be supposed. For example, the 4νCH manifold at ~12 700-cm⁻¹ in the electronic ground-state of C₂H₂ is congested and affected by anharmonic, l-resonance and Coriolis couplings. This complicates intramolecular dynamics and yields unusual forms collision-induced state-to-state molecular energy transfer. Rotational J-states of the (ν1 + 3ν3) or (1 0 3 0 0)⁰ vibrational combination level are monitored by time-resolved infrared-ultraviolet double resonance (IR-UV DR) spectroscopy, addressing the influence of intramolecular perturbations on J-resolved collisioninduced energy transfer with both even and odd ΔJ.
