Abstract
The hyperfine structure of the J=1→0 rotational transitions of 10BH3CO, 11BH3CO, and 11BD3CO was observed with a molecular beam maser spectrometer. Rotational constants, quadrupole coupling, spin rotation, and spin‐spin interaction constants were determined from the data analysis. The deuterium quadrupole coupling constant in 11BD3CO, was determined to be eQqaa(D)=−48.5±2.3 kHz and eQqzz(D)=116.9±5.4 kHz. The procedure for determining the matrix elements of the spin‐spin interaction between the equivalent deuterium nuclei is presented.Keywords
