Abstract
The J = 2 ← 1 transitions of the previously unobserved isotopologues 41K79Br and 41K81Br have been recorded with a pulsed-nozzle Fourier transform microwave spectrometer, newly combined with a 532 nm laser ablation source. Aspects of the experimental design are described. Rotational and nuclear quadrupole coupling constants are obtained and combined with published results for 39K79Br and 39K81Br to produce a set of isotopically invariant parameters. New rotational transitions of 23Na35,37Cl, 39K79Br, and 39K127I have also been recorded. Excited vibrational states are not observed, indicating efficient cooling of the metal halides following the initial ablation event.
