W:Bond order program

 Dear CCL-ers,
 this is to inform you that a new small program called
                         BORDER
 has been prepared for calculating bond order and valence indices, as
 defined in I. Mayer, Chem. Phys. Lett. 97, 270, 1983 (closed shell), ibid.
 117, 396, 1985 (open shell) etc. It can be used at the RHF, UHF level. In
 the case of DFT calculations, the single determinant built up of the
 Kohn-Sham orbitals is considered. The program uses my original bond
 order routine of 1982/83 and some routines from the program APOST by
 I. Mayer and A. Hamza (Budapest, 2000)
 The program requires only a formatted checkpoint file calculated in a
 Gaussian run (G92...G03). It is applicable for large systems (up to 2000
 orbitals) and can easily be extended further.
 The program may be freely downloaded from our website
              http://occam.chemres.hu
 where other programs of our group (energy decomposition, prediction
 of primary mass spectrometric fragmentations etc.) are available, too.
