OVERVIEW
RE_VIEW is essentially a molecular viewer, animator, analyzer, and MOPAC reaction path
converter. The program runs under Windows 3.0 or 3.1, and although the program definitely
benefits from 8 Mbytes (or even more memory) the minimum recommended memory is 4
Mbytes. 

The major functions of RE_VIEW include the ability to:
     1) Display and manipulate molecules in 3D;
     2) Animate reaction pathways;
     3) Align the steps/frames within an animation, along a vectors or onto a plane;
     4) Animate normal modes of vibration;
     5) Monitor geometries (lengths, angles and dihedrals);
     6) Provide tabulated geometrical data (which can be readily incorporated into
         spreadsheets); and
     7) Automatically produce high quality 'ray-traced' images and animation sequences.

RE_VIEW INSTALLATION INSTRUCTIONS
Re_view has been distributed as a zip file and should be unzipped into a directory called re_view. An icon for re_view can then be created and Re_view run in the usual Windows way. (N.B. Many of the options within Re_view require write access to the working directory).

The unzipping process will create the executable file (re_view.exe), a necessary linked library (vbrun300.dll), a manual (in simple text format) and a number of sample input files (see below).

The sample files provided include:
rev_da.qlp - 	a MOPAC (see below) reaction coordinate output file.
bensm_vib.qlp - a MOPAC vibrational analysis output file.
ch2f2.qlp - 	another vibration analysis file.
claisen.xyz - 	a rearrangement reaction (see below)
dipham1.xyz - 	a conformational analysis created using AM1 within MOPAC
antimark.xyz - 	the anti-Markovnikov addition of HCl to propene (see below).   
markov.xyz - 	the Markovnikov addition of HCl to propene (see below).
sn2.xyz - 	a sample Sn2 reaction.
sn2_mod.xyz - 	This example has been generated from the data in sn2.xyz using
		the align and add step options within Re_view.

The following note was provided by the Prof Saethre et. al.:
> We have recently performed reaction pathway calculations on one of the 
> classic organic reactions, namely electrophilic addition of HCl to 
> propylene. We have calculated (SCF/6-31G**) both the Markovnikov and 
> anti-Markovnikov addition, starting from a common molecular complex.

> The first point is a molecular complex which is common for both 
> Markovnikov and anti-Markovnikov.
> The line "FINAL..." now gives the Hartree-Fock energy (kcal/mol) relative 
> to the asymptote of infinite separation of reactants (HCl and propene).

****************************************************************************
Claisen.xyz was provided by:
Dr. Daniel L. Severance" <dan@sage.Syntex.Com>

Dr Severance noted that the data comes from a calculation simulating the gas 
phase Claisen rearrangement. The data comes from a G92 IRC run using the 6-31G(d) 
basis set.

MOPAC is a widely used semi-empirical quantum mechanical program, originally written 
by James Stewart at the Frank J. Seiler Research Laboratory at the USAF Academy. 
It has been ported to a number of different platforms including the PC. A public domain 
version of MOPAC 6.0 has been ported to DOS by Peeter Burk and Ivar Koppel at the University 
of Tartu, Estonia <ivar@chem.ut.ee> and is available by anonymous FTP from ccl.net in the 
directory /pub/chemistry/software/MS-DOS/mopac_for_dos in a zipped form. This zip file
does not include the manual, but you can find it at the same location (ccl.net) in the 
directory /pub/chemistry/documents/mopac_doc.
