Samples thus analyzed had two phase-velocity regions, the normal high-order detonation and an intermediate velocity region. The two abrupt changes in phase velocity are read from the streak records to give the distance to the intermediate region and the distance to detonation. 

Figure 4.10 shows that two approximations, equations (4.3.22) and (4.3.23), become close in the middle of the intermediate region and both are approaching asymptotically equation (4.3.26). Note that the case of multipole... 

Our results taken together with these lower temperature measurements (, l y raise questions which we have attempted to answer using unimolecular and bimolecular reaction rate theory. The first is, simply, are the results at low and high temperature consistent Further, what is the expected behavior in the intermediate region and under what conditions does the direct or addition channel dominate ...

There are two basic instrumental concepts for MS/MS. The first is tandem mass spectrometry in space (or tandem-in-space MS). In order to perform two consecutive mass-analyzing steps, two mass analyzers may be mounted in tandem. Thus, tandem-in-space refers to MS/MS instrumentation where product ion spectra are recorded using spatially separated m/z analyzers. Speedfic m/z separation is performed so that in one section of the instrument ions are selected, then dissociated in an intermediate region, and the products thereof are finally transmitted to a second analyzer for mass analysis (Fig. 9.1). All beam transmitting devices, e.g., multiple sector, ReTOF, TOF/TOF, QqQ, and QqTOF instruments follow this route to tandem MS (Fig. 9.2) [4]. The second approach, tandem mass spectrometry in time (or tandem-in-time MS), enploys a single m/z analyzer (QIT, LIT, FT-ICR) that may be operated by executing the discrete steps of ion selection, activation, and product ion analysis in the very same place but sequentially in time [4]. 

These definitions imply that there will be three copies of atoms in the central region (as they occur in each of the subsystems), two copies of the atoms in the intermediate region and a single copy of the atoms in the outer region. Although there may be multiple copies of some atoms, the coordinates of the atoms in each of the copies are constrained to be the same. To saturate the unsatisfied valencies of atoms arising from the definition of the subsystems, appropriate link atoms are added in the same way as discussed at the beginning of this section. 

Using these expressions for Upzt for the intermediate region and the Newton s law range, one can etisily develop expressions for the particle size corresponding to the critical settling velocity, f/, = Vz, as well as the case of equalsettling particles. Considerable complexity, however, will be encountered in determining Upzt in concentrated suspensions.

These solutions matches logarithmically in the intermediate region and a uniform leading order approximation to the neck shape is unif( f ) = o( ) +, (r) — aln(2r/a) in the vicinity of the (0,0) site.
