He(I) photoelectron spectroscopy of InF

Determination and Study the Energy Characteristics of Vibrational-Rotational Levels and Spectral Lines of GaF, GaCl, GaBr and GaI for Ground State

“…it can be shown that the variation is as in figure (2) which means that the vibrational energy has predominate values in comparison with the rotational energy, all previous results are converge from other researchers values [17,18,19]. After that the spectra lines R(J) and P(J) values have been calculated for gallium halides molecules (GaF, GaCl, GaBr, and GaI) and (1-0) band by using equations (5 and 6), and by depended on spectroscopic constants in table (1). It appears from tables (10,11,12 and 13) and figures (9,10,11 and 12), that the spectral lines values R(J) and P(J) are influenced by difference between B v' and B v'' .…”

“…In the present work, the calculations of the vibrational and rotational energy as a function of vibrational and rotational quantum number , respectively for gallium monohalides molecules (GaF, GaCl, GaBr and GaI) are presented by using computer model and by depended on spectroscopic constants for ground state χ 1 ∑ + for these molecules as shown in table (1). It is seen that B v decreases with increasing v for all molecules and particularly at high values of v for GaF.…”

“…By using equation (2), B v rotational constant for vibrational state for all gallium halides is calculated and figure(1) and table(2) show its variation with the vibrational quantum number v .…”

Potential energy curve study on the3Π electronic states of GaX(X= F, Cl, and Br) molecules

“…For example, the gallium monohalide diatomic molecules GaX (X = F, Cl, Br, I) play an important role as intermediates in the production of new high-frequency and opto-electronic semiconductor devices. [1] Studies of gallium monohalides are currently being carried out both experimentally and theoretically, which have extended and deepened the comprehension of the properties of the electronic states of these molecules. The rotational analyses of bands of the A 3 Π 0+ and the B 3 Π 1 -X 1 Σ systems of gallium monofluoride were studied by Barrow et al, [2] and the results was notable.…”

Determination and Study the Energy Characteristics of Vibrational-Rotational Levels and Spectral Lines of GaF, GaCl, GaBr and GaI for Ground State

“…The gallium monohalides play an important role as intermediates in the production of new high frequency and opto-electronic semiconductor devises [1]. Spectroscopic investigations on the diatomic halides of gallium have been the subject of much interest for a long time [2,3].…”
