Numerical data and functional relationships in science and technology. N.s. / Ed.-in-chief: W. Martienssen Group 2, Molecules and radicals Vol. 19. Molecular constants : mostly from microwave, molecular beam, and sub-doppler laser spectroscopy ; supplemen

Volume II/19 **Molecular Constants mostly from Microwave,****Molecular Beam and Su**b**-Doppler Laser Spectroscopy** is a supplement to the earlier volumes II/4, II/6 and II/14. The slight change in the title reflects current trends in the applications of spectroscopic methods. Together, the four volumes collect all the critically evaluated data published up to 1989/90 on constants of free molecules obtained by classical and modern spectroscopy.The present **Subvolume****II/19** contains high resolution spectroscopic results for freely rotating paramagnetic and ionic molecular species and in Part d3 a substance index for all subvolumes of the volume II/19. 1 Introduction....Pages 1-4 3.2.0 Introduction....Pages 5-5 3.2.1.1 Preliminary remarks....Pages 6-8 C2H....Pages 9-17 C3H....Pages 18-28 C4H, C5H....Pages 29-41 C6H, C3N, C2O....Pages 42-55 C2S....Pages 56-62 NCO....Pages 63-75 NCS, HCCN....Pages 76-86 References....Pages 87-88 3.2.2.1 Preliminary remarks....Pages 89-94 NH2, PH2....Pages 95-109 CH2, HCO, HO2....Pages 110-125 FO2, ClSO....Pages 126-137 PO2, NF2....Pages 138-147 PF2, ArNO....Pages 148-163 References....Pages 164-164 3.2.3.1 Preliminary remarks....Pages 165-167 HCCO....Pages 168-174 c-C3H Part 1....Pages 175-187 c-C3H Part 2....Pages 188-200 CH2F....Pages 201-207 CH2Cl....Pages 208-223 H2NO, CH2CN....Pages 224-237 CH2CHO....Pages 238-253 CH3O Part 1....Pages 254-269 CH3O Part 2....Pages 270-286 CH3S....Pages 287-296 References....Pages 297-297 3.2.4.1 Preliminary remarks....Pages 298-298 HBF{+}, HCO{+}....Pages 299-309 HOC{+}, HN2{+}, HCS{+}, HCNH{+}, HNCCN{+}....Pages 310-318 References....Pages 319-319 3.2.5 Non-linear triatomic molecular ions....Pages 320-326 3.2.6.1 Preliminary remarks....Pages 327-328 H3O{+}, H3S{+}, ArH3{+}, HOCO{+}....Pages 329-345 HONN{+}....Pages 346-354 References....Pages 355-355 1 Introduction J.

The slight change in the title reflects current trends in the applications of spectroscopic methods. Together, the four volumes collect all the critically evaluated data published up to 1989/90 on constants of free molecules obtained by classical and modern spectroscopy. The present Subvolume II/19 contains high resolution spectroscopic results for freely rotating paramagnetic and ionic molecular species and in Part d3 a substance index for all subvolumes of the volume II/19. Volume II/24 is a supplement to volumes II/4, II/6, II/14, and II/19 and is planned to appear in five subvolumes, the last of which will contain the substance index taking into account all molecules worked at since 1967 in the volumes mentioned and will provide cross references to and between all tables of these. This subvolume contains a general introduction and tables of rotational and centrifugal distortion constants for diamagnetic asymmetric top molecules.
