CONSTANTS FOR MOLECULES OF ASTROPHYSICAL INTEREST
	      IN THE GAS PHASE: PHOTODISSOCIATION,
		 MICROWAVE AND INFRARED SPECTRA.


The molecular data compilation may be obtained from 
http://wwwusr.obspm.fr/~crovisie/basemole/

	The following ASCII files are in the directory:

base-readme.txt	present text (plain ASCII)
intro42.rtf	introduction, description and index of the compilation 
		(~17 pages)
intro42.ascii	idem, in plain ASCII
moletot42.rtf	the compilation itself (~272 pages)
moletot42.ascii	idem, in plain ASCII
trimole40.rtf	a sorted list of vibrational bands (12 pages)
trimole40.ascii	idem, in plain ASCII

	The files to use are those in the RTF format (those with the .rtf
extension).  They are intended to be transferred to a Mac or a PC and 
treated with WORD (or a compatible word processor).

	The files were originally created by WORD (Version 5) on a Mac. 
Because WORD for Mac and for PC are not fully compatible, a few minor 
defects appear when displaying the compilation on a PC.

	Files in plain ASCII (those with the .asc extension) are also provided. 
Their use is discouraged, since special characters, tabulations etc... are 
lost. They could be helpful if the other files cannot be used or for 
accessing the data with, e.g., sorting programs.

	The compilation is intended to be regularly updated. The present 
version (4.2) is that of May 2002.

	In the future, it is intended to convert this compilation into LaTeX
(for improved presentation, more versality and independence from commercial 
word processors) and to provide an hypertext version.
