Abstract
The I-atom atomic resonance absorption spectrometric (ARAS) technique has been used in Kr bath gas to study the thermal decomposition kineti cs of iodobenzene, C6H5I, over T- and P-ranges of 1082-1416 K and 103- 731 Torr, giving the first order expression, k(+/-60%) = 1.982 X 10(11 ) exp(-23120K/T) s(-1). Two unimolecular theoretical approaches were u sed to rationalize the data implying E-0 = Delta H-0(0) = (66.7 +/- 0. 7) kcal mol(-1) and [Delta E](down) = (447 +/- 92) cm(-1).
