Dear Chemists:
I post this question to request your help.

50 years ago, H. C. Thomas published a paper titled ``Heterogeneous Ion
Exchange in a Flowing System'', J. Amer. Chem. Soc., Volume 66 (1944) 1664-
1666.  On the Thomas equation, the most recent paper we have seen is R. R.
Rosales, Stud. Appl. Math., Volume 59 (1978), 117-151.
   The Thomas equation is mathematically interesting to my wife (Bo Tian,
an associate professor of computer sciences at Lanzhou University).
   Could you kindly give us some information on the chemical developments
or changes on top of the Thomas theory since 1978?  A few words of comments
or a small list of reference papers would be just wonderful.
   Thank you a million.
                            Yi-Tian Gao
                            Professor of Physics, Lanzhou University

P.S.  I am not able to become subscribed to the list.
      Please *directly* reply to  WANGXL@BEPC2.IHEP.AC.CN

Dear DR. Ross underhill,
              your question is very pertinent to all the people
  doing computational chemistry and the methods currently available
                  	i know too little to express my own opinion
  in this matter, however I request you to summarize all the responses
   to net as you migth get in the coming days from experienced people.

Subject: MO vis. program needed


At the Washington D.C. ACS meeting in August I heard a Dr. D. L.
Lichtenberger from the University of Arizona speak in the "Bonding
Models in Chemistry" session.  After the talk he mentioned that he had
a program which people could get via ftp which allowed them to
visualize Molecular Orbitals, maybe as bonding contours or something.
Unfortunately, I got distracted and never got the ftp address or his
email address.

Does anyone know which program this might be and/or what the ftp site
address is?

The program I'm using, PSGVB, can output MOs in Gaussian 92 format so
if you know of other freeware or shareware programs which can take MOs
in a G92 format and display them graphically, that would be great too.
Platforms of interest are SGI, IBM RS/6000, and Sun.

Thanks in advance and please email any reponses to
bryan@chem.columbia.edu.  I will post a summary if desired.
