“…The HC1 experimental integrated oscillator strengths obtained from Hayes and Brown (30) and Ninomiya et al (29) agree reasonably well for 200-205.3 eV, within the experimental error given in ref. 30, while the mixture rule result is some 50% higher.…”

“…As E increases, between 205.3 and 208.7 eV, the integrated oscillator strengths obtained from ref. 30 and the mixture rule agree within the estimated experimental error whereas the results due to Ninomiya et al (29) apparently become too low and this trend continues between 208.7 and 280 eV. It seems that the disagreement between the mixture rule and the experimental data between 200-205.3 eV, within -3 eV of the Chlorine L?…”

This paper is dedicated to Professor Camille Sandorb on the occasion of his 65fh birfhdayASHOK KUMAR and WILLIAM J. MEATH. Can. J. Chem. 63, 161 6 (1985). Dipole oscillator strength distributions have been constructed, and used to evaluate integrated dipole oscillator strengths and a variety of dipole oscillator strength properties, for ground state Ne, Ar, Kr, Xe, HF, HCI, and HBr. Each distribution has been constructed by using experimental and theoretical photoabsorption cross sections and by subjecting the resulting dipole oscillator strength data to constraints provided by the Thomas-Reiche-Kuhn sum rule and molar refractivity or related data for the relevant dilute gases. The resulting dipole properties are generally the most or only reliable values available for the hydrogen halides, for the rare gases they largely augment reliable results for most of the properties already available in the literature. The results for HCI are used to discuss an interesting molecular effect in the photoabsorption spectrum of this molecule betwen -200 eV and -205 eV.ASHOK KUMAR et WILLIAM J. MEATH. Can. J .

Dans le cas des halogenures d'hydrogene, les propriCtCs dipolaires qui en rksultent sont gCnCralement les seules valeurs disponibles ou les plus fiables; pour les gaz rares, les risultats fiables sont grandement augmentCs pour la plupart des propriCtCs qui sont dCja disponibles dans la litterature.

“…The photon energies at which the 2 p 5 * states were excited, were calibrated from a measured total electron yield spectrum with the aid of a published absorption spectrum. 7 The kinetic energy of the electron spectra was then calibrated using the binding energy of the 2 electron ͑E b ϭ 12.748 eV͒. Figure 1 presents the Auger electron spectra that result from the decay of the 2p 3/2 3 * ͓curves ͑b͒ and ͑c͔͒ and 2 p 1/2 1 * ͓curves ͑d͒ and ͑e͔͒ states of the HCl and DCl molecules.…”

“…[1][2][3][4][5] Various core-excited states of the HCl or DCl molecule can be created by photons with energy slightly below the Cl 2p ionization threshold. 6,7 The 2 p absorption spectrum shows a series of sharp peaks assigned to the excitations to the orbitals that have atomic character, and a much broader feature at lower photon energies that is due to the excitations to the antibonding * molecular orbital. These core-excited states decay mainly via Auger transitions.…”

High-resolution Auger electron spectra from the decay of the Cl 2 p→* excitation in HCl and DCl have been measured. The spectra are analyzed, separating molecular and atomic features, which are assigned to transitions to the HCl ͑52͒ 4 * and Cl (3s3 p) 6 states, respectively. Auger line shapes, as affected by the molecular dissociation, are studied by comparing the experiment with the results of Monte-Carlo computer simulations based on a semiclassical model.

“…Several theoretical investigations on this HCl spectrum have also been published. 3,15,[19][20][21] As they neither consider electron correlation effects in detail, nor account for the spin-orbit splitting explicitly, the transition energies are only of qualitative accuracy with errors of the order of several eV. Neither do these studies provide a detailed understanding of the spectral features that can be seen in modern highresolution experiments.…”

This is applied to the absorption spectrum of HCl at the 2p→6*, 4s, 4p, 3d, and 5s resonance energies. All input data for the spectrum are obtained from ab initio calculations. These are ͑i͒ the nonrelativistic energies and transition probabilities of the contributing states, ͑ii͒ the spin-orbit coupling parameter, and ͑iii͒ the total Auger transition rates of the core excited states. The prior theoretical finding that the total Auger decay rate depends substantially on the core hole orientation is supported by a comparison of the theoretical and experimental absorption spectra. Furthermore, the preferred orientation of the core excited HCl molecule with respect to the molecular bond axis is discussed. General considerations about intensity ratios between corresponding states with 2p 3/2 and 2p 1/2 holes are given on the basis of the theoretical framework.
