Landolt-Börnstein Group 2 Molecules and radicals Vol. 24. Molecular constants : mostly from microwave, molecular beam, and sub Doppler laser spectroscopy ; supplement to volumes II/4, II/6, II/14, and II/19 / ed.: W. Hüttner Subvol. C. Dipole moments, q

Volume II/24 presents the spectroscopic data on diamagnetic and paramagnetic molecules as well as on molecular ions and radicals up to date considering the publications up to and partly including 1997. The spectroscopic information collected in this volume has been obtained principally from gas phase microwave measurements. In addition, gas phase data have been included derived from methods related to microwave spectroscopy by employing a coherent radiation source. These are molecular beam techniques, radio frequency spectroscopy, electron resonance spectroscopy, laser spectroscopy, double resonance and saturation techniques. Some other methods are considered if the accuracy of the derived molecular parameters is comparable to that of microwave spectroscopy owing to a good statistics in the analysis of data, and no microwave data are available. Examples would be Fourier infrared spectroscopy or laser induced fluorescence. 1 Introduction 1 1.1 General remarks 1 1.2 Review articles and tables 1 1.3 Arrangement of tables, substances, and parameters 2 1.4 Selection of data 3 1.5 Abbreviations used for experimental methods 4 1.6 Selected fundamental constants and conversion factors 4 1.7 CD-ROM 6 1.8 References for l 6 2 Constants of diamagnetic molecules 7 2.6 Dipole moments 7 2.6.1 Diatomic molecules H.
