The fluorescence lifetime, rf, of 9-cyanoanthracene (9CNA) in the supercritical fluid (SF) of Xe (6.8 MPa at 293 K) is found to be 2.39 \_ 0.13 ns, which is much shorter than the 17.78 \_+ 0.43 ns measured in SF of CO 2. This large decrease in Tf is interpreted in terms of the vibronic-level-depende
