Abstract

Direct measurements of the dissociation of I₂ molecules at the optical axis of a supersonic chemical oxygen-iodine laser (COIL) as a function of I₂ flow rate were carried out. This enabled us to determine the number of consumed O₂(¹Δ) molecules per dissociated I₂ molecule. The number depends on the experimental conditions: it is 4.2±0.4 for typical conditions and I₂ densities applied for the operation of the COIL, but increases at lower I₂ densities. Possible dissociation mechanisms consistent with our results are discussed and the importance of dissociating I₂ prior to its mixing with O₂(¹Δ) is stressed.
