Franck-Condon factors and r centroids of the²Σ⁺-x²Σ⁺band system of AlO using RKR potentials

Franck—Condon factors,r-centroids and electronic transition moment variation with internuclear distance of theA 1Σ−X 1Σ band system of BaO using RKR potentials

“…This recent outlook has given rise to new experimental techniques and recourse to better potential energy functions in this field of electronic band spectra of diatomic molecules. The results and conclusions of such studies on (2Z --X2Z) bands of Al0 molecule reported recently by TAwvE and TULASIGERI [5] are illustrative of this point.…”

“…After the manner shown by TAWDE and TULASIGERI [5] on their work in Al0 u.v. band system, calculations have been made of the turning point values rmi n and rma = with MOrtSE and RKR potential energy functions in the case of the two electronic states A1Z and X1Z of the transition involved of the BaO band system.…”

“…%-test and Bv-test as those employed by TAwov, and TUrASir [5]. For these tests as shown by them calculation of theoretical % value has been made from the expression derived by PEKVRIS [13] using MoasP, potential and that of Bo from the theoretical relation of JAR~tAIN [14], using the computed normalised wave functions for the two potentials R K R and MORSE.…”

“…The values thus obtained are entered in Table V at column 2 side bv side with corresponding MORSE potential values of WALVEKAR [12] entered in column 3 of the same Table. Table V Franck--Condon factors and r-centroids of the AI.~,--X1Z band system of BaO using R K R potentials These are computed for the present BaO system using the RKR potential by the direct method of NICHOLLS and JARMAII~ [15] in the same way as done by TAWDE and TULASIGERI [5]. During the course of these calculations, it was noticed that our computed results by RKR potential particularly for (0,1) and (1,2) bands relative to others were far away from the values of WALVE-KAR [12] by MOnSE potential.…”
