Paper Abstract

Utilizing the cube-corner mirrors in FTIR-spectrometers has rendered possible to record the interferogram over very long mirror displacements and extend the best resolving power to 10-3 cm-1. Simultaneously the accuracy of the line positions is better than 10-5 cm-1. These extreme accuracies are needed especially in creating a set of reliable IR-line frequency standards to be used to calibrate other infrared devices. Therefore, it is very important to analyze all the possible sources of errors and find the best ways to eliminate them.
