• CO<SUB>2</SUB> TEA laser-induced photolysis of C<SUB>2</SUB>H<SUB>5</SUB>F was studied by using a time-resolved infrared fluorescence technique. Molecular elimination of vibrationally excited hydrogen fluoride (HF<SUP>*</SUP>) from C<SUB>2</SUB>H<SUB>5</SUB>F<SUP>*</SUP> occurs in the process. Rotational temperatures and vibrational level populations of HF<SUP>*</SUP> are estimated from observed fluorescence spectra by computational fitting. Higher vibrational levels are populated to a less extent in the decomposition under a collisionless condition. When the pressure of C<SUB>2</SUB>H<SUB>5</SUB>F is increased, however, population inversion is allowed among some levels. Possible reaction mechanism is discussed for the production of HF<SUP>*</SUP> at extraordinarily high vibrational levels.
