Infrared chemiluminescence studies

One flow system that has been designed to minimise the effects of relaxation and is commonly used in infrared chemiluminescence studies is designated the arrested relaxation system [77]. Figure 2 shows an... 

An infrared chemiluminescence study [501] of the reaction 0(3P) + CH3 shows that it is direct with the formaldehyde product being highly vibrationally excited. A lower limit of (Fv) > 0.43 has been placed on this excitation. The high pressure reactions of 0(3P) atoms with various hydrocarbons show emission of vibrationally excited OH(d < 14) radicals which is attributed to the reaction [ 502]... 

These concepts have been applied by Ben-Shaul et al., 1972a, b to analysis of product energy distributions and to the definition of apparent temperatures for non-equilibrium product distributions. Their procedure may be illustrated with a treatment of vibrational distribution of products, as measured in infrared chemiluminescence studies. The quantities measurable in this case are and v. It is convenient to introduce fractional energies fx = EJE, where fT + fv + fR = 1. The probabilities actually determined are conditional probabilities P(/v ) for fixed . The surprisal is...

Much of the information concerning the distribution of vibrational and rotational excitation energies in reaction product molecules necessary for the development of present chemical lasers has come from infrared chemiluminescence studies with molecular beams/ " The arrested relaxation technique developed by Polanyi and co-workers ° provided detailed rate constant data for many successful chemical laser systems.
