Hello,

Im looking for any information about a program that was part of the Quantum=
Chemistry Program Exchange in the 1970s (submitted around 1975):

S. Chapman, D. L. Bunker, A. Gelb, QCPE Program No. 273, Indiana University= ,
Bloomington

The program was known as 'A + BC'.

For context, Im the son of one of the authors (Don Bunker) and would very m= uch
like to locate, revive, and run this code. From what I understand, it was u= sed
by a number of groups for semiclassical trajectory calculations in that era= .

Im not a chemist by training, but I have a background in high-energy physic= s
and computational physics, so Im hopeful that I can reconstruct and preserv= e
the program for my family records.

This is a personal project, and I would be grateful for any suggestions, le= ads,
or contacts that might help me track down QCPE Program 273 or any surviving=
documentation.

Many thanks,

Brian Bunker
