Beschreibungen/Notizen

• Accurate high-resolution spectroscopic measurements require secondary standards which can serve as convenient calibration references in laboratory and field research. We have measured the frequencies of a series of rotational transitions between 0.3 and 6 THz for several stable and readily obtainable gases (CO, HCl, and HF) to an accuracy better than one part in 10 7 and present revised rotational constants for these molecules. The gases were selected (in part) due to their presence in the Earth's atmosphere in significant amounts and thus are convenient for the frequency calibration of atmospheric spectra.
