ADDITIONS AND CORRECTIONS 1996, Volume 100 Thomas L. Allen,* William H. Fink, and David H. Volman : Theoretical Studies of the Mechanism of the Gas Phase Reaction of the Hydroperoxo Radical with Carbon Monoxide to Form Hydroxyl Radical and Carbon Dioxide Page 5299. In line 4 of the Abstract, there is a minus sign missing from each of the two numbers. They should be -242.7 and -246.1. JP962648X
V. Pershina* and B. Fricke: Group 6 Dioxydichlorides MO2Cl2 (M ) Cr, Mo, W, and Element 106, Sg): The Electronic Structure and Thermochemical Stability Page 8748. In the third line of the abstract, O2Cl2 should be replaced by SgO2Cl2. JP963483V

Due to a proofreading error, some incorrect values for [C2H2]∞ were reported. However, the values for [C2H3]0 and [C2H2]∞/[C2H3]0 were correct as originally published. Table 3 with the correct [C2H2]∞ values is presented below.
