Configuration Mixing



 Dear Netters,
 	I am intererested in calculating the contribution of various
 configurations such as (D(+)A(-)), D(*)A, (D(-)A(+)) etc. for a
 metathetic reaction B---H + B-----> B---H---B ---> B + H---B and
 H----B----H reactions where [D=(H-B) and A=H or B] in VALENCE BOND
 mode.  Does anyone have a program to calculate the energies and wave
 functions in the valence bond mode for the above mentioned configurations?
 I need to know the contributions of various configurations in a
 metathetic reaction.
 	Thanks in advance and mail your answers to the following
 e-mail address.
