Molecular Dynamics of Photodissociation: Quasidiatomic Model for ICN
TL;DR: In this paper, a model for the photodissociation of ICN in its lowest continuum is developed and is used to predict the partitioning of available energy between translational, rotational, and vibrational energies of the recoiling fragments.

Photodissociation of molecular beams of methylene iodide and iodoform
TL;DR: In this article, the angular distribution of CH2I2 and CHI3 has been measured and it has been shown that the lower lying excited states of CH 2I2 can dissociate to give an iodine atom and the corresponding radical.

T. Donohue,John R. Wiesenfeld +1 more
TL;DR: In this paper, the branching ratios for formation of I (5'2P1/2) and I (2'5P3/2 ) following broad-band photolysis of a number of alkyl iodides and their fluorinated and deuterated analogs have been directly determined using time-resolved atomic absorption spectroscopy.

Formulas and Numerical Tables for Overlap Integrals
Abstract: Explicit formulas and numerical tables for the overlap integral S between AO's (atomic orbitals) of two overlapping atoms a and b are given. These cover all the most important combinations of AO pairs involving ns, npσ, and npπ AO's. They are based on approximate AO's of the Slater type, each containing two parameters μ [equal to Z/(n—δ)], and n—δ, where n—δ is an effective principal quantum number. The S formulas are given as functions of two parameters p and t, where p=½(μa+μb)R/aH , R being the interatomic distance, and t=(μa—μb)/(μa+μb). Master tables of computed values of S are given over wide ranges of p and t values corresponding to actual molecules, and also including the case p=0 (intra‐atomic overlap integrals). In addition, tables of computed S values are given for several cases involving 2‐quantum s, p hybrid AO's.Hybrid S values for any desired type of hybrid can be obtained very easily from the tables as simple linear combinations of non‐hybrid S values. It is shown how S values correspondin...

Intensities in Molecular Electronic Spectra X. Calculations on Mixed‐Halogen, Hydrogen Halide, Alkyl Halide, and Hydroxyl Spectra
TL;DR: In this article, the dipole strengths for certain perpendicular-type transitions N→Q in the mixed halogens, the hydrogen and monovalent metal halides, and the alkyl halides are calculated theoretically by the LCAO and by the AO approximations.
