Abstract
A homemade TEA CO, laser tuned to the 10P(48) line, 10.91 mu m, was us ed to excite the v(4) mode of CDCl3 (914 cm(-1)). The IR fluorescence signal from the CDCl3 2v(5) overtone band (1492 cm(-1)) was isolated b y means of a gaseous filter. The temporal variation of this fluorescen ce emission was studied as a function of the laser fluence. Under high excitation conditions, non-linear effects become obvious, and measure d rate constants greater than predicted from linear kinetic rate equat ions have been found.
