Rotational collision numbers, table

DC1, HF, and DF, rotational collision numbers appear to decrease with increasing temperature over the intervals for which data are available (see Table 3.2). His comparison of acoustic-absorption and thermal-conductivity data for both HC1 and H20 indicates consistent results for these two experimental methods and their respective interpretations. However, the apparent decrease of Zr with increasing temperature is in contradiction to Zeleznik s... 

Table 1. Lennard-Jones (12 6) potential parameters (mostly from Svehla, 1962), rotational collision numbers Cij, and polarizabilities 0L of nonpolar species of interest in combustion systems, together with Stockmayer parameters of H2O (Mason and Monchick 1962).

Application of the symmetry correlation scheme to reaction (12) is summarized in Table 4 where N is the Himd s coupling case (b) rotational quantum number for O2 and - 5 is the difference of the Hund s coupling case (a) quantum numbers of total angular momentum and electron spin (5 = 1/2) angular momentum, respectively. To consider the high-symmetry isotopomer system first, the results in Table 4 indicate that only odd / collisions - 5 = odd) with 2 can lead... 

The effects of a number of substituent groups on the fluorescence of aromatic compounds are listed in Table 2.3. There are exceptions to this table since a number of other factors must be considered. For example, molecules which are able to rotate, bend or twist have a tendency to lose energy from the excited state through molecular collision and other vibrational processes. It is not possible to compile a complete set of rules for determining whether a molecule will fluoresce, as there are many anomalies. 

Tables 8-12 show that the cross sections for energy transfer to states far removed from the initial state are reasonably large, so that large-Av or large-Aj transitions are not unlikely in H + H2 collisions. We also reported vibrational transitions with large quantum number changes for Ar + H2 at a collision temperature of 4500 in that study the initial rotational state of H2 was...
