Abstract

A homemade TEA CO2 laser tuned to the 1OP(48) line, 10.91 μm, was used to excite the v4 mode of CDCl3 (914 cm-1). The IR fluorescence signal from the CDCl32v5 overtone band (1492 cm-1) was isolated by means of a gaseous filter. The temporal variation of this fluorescence emission was studied as a function of the laser fluence. Under high excitation conditions, non-linear effects become obvious, and measured rate constants greater than predicted from linear kinetic rate equations have been found.
