“…However, this study also focuses attention on the paucity of information con-J.L. The antimony halides SbBr, 39 SbCl, 40 and S b F , A 1^2 especially the fluoride, are particularly intriguing. The value quoted for the AsF bond strength is based on a theoretical calculation-30 supported by limited experimental data.…”

“…This relationship is exact if Rc(r) is linear, in which case Rc(r) may easily be shown to be the value of Re(r) at the "r-centroid", f, given by f = § 'V'lv dr/ f dr (7) Provided that the difference between upper and lower state potential curves is monotonic in the region of significant wave function overlap, semiclassical arguments imply that transitions associated with a given vibronic band will occur predominantly at a single intemuclear separation. The relative intensity of each vibronic band will therefore indicate the strength of the electronic transition moment at the dominant value of r, which may be identified with Rfr) in eq 6.…”

Vibrational transition probabilities have been measured for the B2Z+(u'=0_3)"2~(~''=Ck10) and B'2A(u'=0, 1)-X211(u"=0_2) systems of SiCl. Individual vibronic levels of the excited states were prepared by laser excitation of ground-state Sic1 formed in a discharge-flow system, and the resultant emission was dispersed and recorded. Independent measurements made in two laboratories were in very satisfactory agreement. The extensive results for the B-X system were compared with Franck-Condon factors derived from Rydberg-Klein-Rees potentials, allowing the form of the electronic transition dipole moment function to be assessed. It was found that the electronic transition probability for the B-X system is relatively slowly varying with internuclear distance, consistent with previous conclusions on the electronic configurations of the states involved. The more limited data on the strongly diagonal Bf-X system were not readily reproduced from the accepted form of the potentials and the anticipated electronic transition dipole moment.

“…(L(Si)= 85 kcal mole-1). D(SiC1) was taken as 4.2 ev (Herzberg 1939, Jevons 1936) so that levels f and e are also fixed. The setting of levels c and d which involves D(SiC1,) is not so satisfactory.…”

T h e report deals with certain experimental and theoretical aspects of collision processes in polyatomic molecular gases. Experimental techniques, dating from about 1932, are reviewed, with more attention given to recent methods. Measurements of critical potentials, cross sections, and initial kinetic energy of product fragments are described.A survey of the theoretical implications of these data is then given, with reference to the significance of electron-impact ionization potential measurements, for molecules and free radicals, bond dissociation energies for a wide range of molecular types, and certain collision processes involving negative ions. 0 2. EXPERIXENTAL TECHNIQUES Early measurements of ionization potentials have been reviewed briefly by Arnot (1933) and more recently and fully by Massey and Burhop (1952) in their critical and comprehensive work. Figure 2 (Tate and Smith 1932) shows an apparatus using collimation of the electron beam by a magnetic field (Jones 1927) suitable for measurements of ionization cross sections and critical ionization potentials. The electrons are accelerated from the filament F through a collimator system into the ionization space between electrodes P, and P,. Ionization produced here is measured as a current to P, and P, and the onset of this current gives the first ionization potential. Cross sections for ionization are determined
