M. Paplewski et al., THE MILLIMETER-WAVE SPECTRUM OF PH2BR - FIRST DETECTION OF A PREVIOUSLY UNKNOWN MOLECULE, Chemical communications, (17), 1996, pp. 2015-2016
The short-lived molecules (PH2Br)-Br-79 and (PH2Br)-Br-81 are detected
for the first time thanks to millimetre-wave spectroscopy allowing de
termination of accurate rotational and centrifugal distortion constant
s; these are found to be in good agreement with ab initio predictions.
