The vibrational predisso&tion spectra of (C, H4)2 and Ar-C? H4 hwc been measured using a molecular beam apparatus and ;t tunable infrared laser (an optical parametric oscillator), near the vg (==3100 cm-') and 1~11 (=2990 cm-') modes of ethylene. The spectra are not homogeneously broadened and show
