Studies of Elementary Processes and Coupling Involved in the D2/F2 Chemical Laser.
Abstract
The performance of a H2/D2 chemical laser is a function of the nascent energy disposal parameters for the F + H2 (D2) and H (D) + F2 chemical reactions and the vibrational relaxation of HF (DF). Chemiluminescence Mapping (CM) in which chemical components are observed by their spectral and time resolution is a technique which is capable of providing fundamental information on both nascent energy distributions for bimolecular exchange reactions and vibrational relaxation. Knowledge of the reactants (atoms or ions) and residence times must be known in order to interpret the data. Using a double floating probe the ion content flowing from a microwave discharge of hydrogen was found to be <.0000018 of the total flow, thus ion molecule reactions are unimportant. The interpretation of CM experiments requires realistic modeling to deconvolute the experimental data. Both types of CM experiments provide nascent vibrational energy distributions. CM-LP experiments also provide total reaction rate constants and microscopic relaxation rate constants. In addition to the F + H2(D2) benchmark reactions, experimental results for H(D) + F2, F + HBr, and F + CH2C12 are discussed and compared to other studies when available.
