Dependence of the rate constants for electron attachiment to CHCI, on mean electron energy from thermal to about 2 eV have been investigated at ambient temperatures between 223 and 600 K using the pulse-radiolysis microwave cavity method combined with microwave heating. The rate constant at thermal energy incrases prominently with temperature with an ativation energy of 0.13 ±0.01eV which is obtained by Arrhenius plot of the present rate constants. The atachiment cross sections obtained by unfolding the rate constants show two peaks at 0 and 0.8 eV at 223 K, but a peak observed at 0.8 eV at 223 K cannnot be seen at 600 K. The importance of vibrationally excited states in the deformation mode of CHCI_3 has been proposed to interpret the cross sections observed at 600 K.
