Combined hyperbolic inverse power

Putting Together the Pieces A Global Description of Valence and Long-Range Forces via Combined Hyperbolic Inverse Power Representation of the Potential Energy Surface... 

This chapter is organized as follows. The approach highlighted here is described in section 17.2. Due to the special class of basis functions employed for the least-squares fit, the method is named combined hyperbolic inverse power representation or CHIPR from its initials, and uses the MBE as the starting point. Still in its infancy, the approach has been tested so far on tria-tomic systems that have been much studied by other schemes, namely H3 and HO2. Reasons for their choice are pinpointed in section 17.3, where the results obtained are reviewed. Section 17.4 gathers the concluding remarks and prospects for future work.
