Letters, 135, 432(1987)Author Institution: Laboratoire de Chimie Physique Molculaire CP. 160, Universite Libre de Bruxelles, Faculte des Sciences; Herzberg Institute of Astrophysics, National Research CouncilThe $\tilde{a}^{3}A_{u}-\tilde{x}^{1}Ag$ transition of $C_{2}H_{2}O_{2}$, observed around $5200 {\AA}$, was recorded with the help of a Fourier Transform Spectrometer at Ottawa. with a resolution of $0.020 cm^{-1}$. Doppler limited and sub Doppler laser investigations are being undertaken at Brussels in order to allow the analysis of this very dense spectrum. They are based manly on the infrared Optical Double Resonance technique, after (1,2) and also on the inter Modulated Phosphorescence, Laser Induced Phosphorescence and Stark Modulation techniques. Preliminary results will be presented
