Abstract
The progress of photochemical chain reactions can be monitored with the chemically amplified optoacoustic effect. Measurement of the acoustic amplitude as a function of time in H 2 — Cl 2 and D 2 — Cl 2 mixtures irradiated with the 488nm output of an Ar ion laser gives a profile of reaction rate versus time. Measurement of the relative rates of reaction for H 2 and D 2 with Cl 2 obtained from the optoacoustic data along with thermochemical data permits relative rate parameters for these two reactions to be determined.

In the absence of measured values of k4, it can be assumed that this constant changes only insignificantly from H2 to D2. See Ref 7.
