Dissociative electron attachment and Ar+ reaction with chromium hexacarbonyl, 296–400 K.

Dissociative electron attachment rate constants have been measured for Cr(CO)₆ under thermal conditions, 296–400 K, yielding Cr(CO)₅⁻ product. At 296 K, 2.92 ± 0.70 cm³ s⁻¹ was measured and a small decrease with temperature was observed (2.72 ± 0.70 cm³ s⁻¹ at 400 K). We additionally determined the cation products of Ar⁺ reacting with Cr(CO)₆. [ABSTRACT FROM AUTHOR]
