Sorbie-Murrell function

Spectroscopic parameters are obtained by fitting the PES to the Murrel-Sorbie (MS) function ... 

Murrell and Sorbie have proposed an extended Rydberg function as... 

Sorbie and Murrell have developed a function for triatomic systems based on a many body expansion of PE. It has been applied to repulsive potentials as well and has become an attractive option for fitting ah initio PES. It has sufficient flexibility and extendable to higher polyatomic systems and to two-valued surfaces. The potential for triatomic system is decomposed into one-, two- and three-body terms. The potential is given as... 

Fig. 13.3. (cont.) and (13.7). The wavefunctions are calculated using the empirical fit PES of Sorbie and Murrell (1975). The arrows indicate qualitatively the route of the evolving time-dependent wavepacket in the excited state. The dashed contours in (a) and (b) represent the A-state PES. Right-hand side The corresponding absorption spectra as functions of the energy in the excited electronic state. E = 0 corresponds to three ground-state atoms, H + O + H. Within this normalization the lowest eigenvalue of H20(A) is -9.500 eV. 

Fig. 2 shows the diabetic laser dressed PESs between the lA and 3A states for the laser wavelength x 700 nm. The PESs are fitted to Murrell and Sorbie type analytical functions [9]. In...
