==== This directory contains data related to spectroscopic projects performed in the Cologne Laboratories ====

The individual directories contain files to be used with the Pickett program (among them line and parameter files; in some cases additional files, such as fit files, are provided). In many instances the respective directories contain data of several isotopomers and several vibrational states which may be put in separate subdirectories.

Currently, information on the following molecules can be obtained:
