Collision-induced state-to-state molecular energy transfer between rovibrational states in the 12 700 cm(-1) 4ν(CH) manifold of the electronic ground state (X) over tilde of acetylene (C2H2) is monitored by time-resolved infrared-ultraviolet double resonance (IR-UV DR) spectroscopy. Rotational J-states associated with the (ν(1) + 3ν(3)) or (1 0 3 0 0)(0) vibrational combination level, initially prepared by an IR pulse, are probed at ∼ 299, ∼ 296, or ∼ 323 nm with UV laser-induced fluorescence via the (A) over tilde electronic state. The rovibrational J-states of interest belong to a congested manifold that is affected by anharmonic, l-resonance, and Coriolis couplings, yielding complex intramolecular dynamics. Consequently, collision-induced rovibrational satellites observed by IRUV DR comprise not only regular even-&UDelta; J features but also supposedly forbidden odd-&UDelta; J features. A preceding paper (J. Phys. Chem. A 2003, 107, 10759) focused on low-J-value rovibrational levels of the 4ν(CH) manifold (particularly those with J = 0 and J = 1) whereas this paper examines locally perturbed states at higher values of J (particularly J = 17 and 18, which display anomalous doublet structure in IR-absorption spectra). Three complementary forms of IR-UV DR experiments (IR-scanned, UV-scanned, and kinetic) are used to address the extent to which intramolecular perturbations influence the efficiency of J-resolved collision-induced energy transfer with both even and odd &UDelta; J.
