Abstract

Time-resolved, fluorescence-detected infrared-ultraviolet double resonance (IR-UV DR) techniques were used to investigate the spectroscopic and dynamical behavior of acetylene molecules in two rovibrational manifolds: v _CC+3v _CH at approximately 11 600 cm ^-1 and 4v _CH at approximately 12 700 cm ^-1. The high symmetry and structural simplicity of the C ₂H ₂ molecule suggest that its behavior at these chemically insignificant levels of excitation should be regular and predictable. However, the IR-UV DR spectroscopic experiments in these regions reveal numerous puzzling anomalies.
