| Description
| - Byla změřena rotační spektra dvou izotopických modifikací brom-methylového radikálu CH279Br a CH281Br v jejich základním elektronickém stavu 2B1 ve frekvenční oblasti 180-470 GHz, odpovídající a-typu přechodu z N=8-7 na N=21-20. Radikál byl produkován pomocí oddělení vodíku z methyl-bromidu (CH3Br) chlorovými nebo fluorovými atomy v otevřeném prostoru kyvety. V naměřeném spektru byla rozlišena hyperjemná struktura, způsobená jádry bromu a byly velice přesně stanoveny rotační konstanty jako i konstanty jemného a hyperjemného štěpení pro oba izotopomery. Vnitřní defekt byl určen 0,02896(20) a 0,02895(20) amu A2 pro CH279Br a CH281Br, resp., ukazující na planární strukturu. Při fixování úhlu HCH na 124,5o lze odvodit efektivní molekulovou strukturu jako r0(CBr)=1.848 A a r0(CH)=1,084 A. Porovnání molekulových struktur různých methylradikálů (substituovaných halogeny) je diskutováno vzhledem k planaritě těchto radikálů. (cs)
- The rotational spectra of the two isotopic species of the bromomethyl radical, (CH2Br)-Br-79 and (CH2Br)-Br-81, have been observed in their ground electronic state B-2(1) in the 180-470 GHz frequency region, corresponding to a-type transitions from N=8-7 to N=21-20. The radical was produced by hydrogen abstraction of methylbromide (CH3Br) either by chlorine or by fluorine atoms in a free space cell. Hyperfine structure due to the bromine nucleus has been resolved in the observed spectra, and the rotational constants as well as the fine and hyperfine interaction constants were accurately determined for both isotopomers. The inertial defect was determined to be 0.028 96(20) and 0.028 95(20) amu angstrom(2), for (CH2Br)-Br-79 and (CH2Br)-Br-81, respectively, suggesting a planar structure. By fixing the angle HCH bond angle at 124.5 degrees, an effective molecular structure can be derived as r0)(CBr)=1.848 A and r(0)(CH)=1.084 angstrom.
