Popis:	The millimeter wave spectrum of the unstable halofulminate BrCNO was observed in a low-pressure pyrolysis of Br 2 CNOH. Ground-state rotational constants of 79 BrCNO and 81 BrCNO were determined to be 1739.930 07 (10) and 1726.961 86 (11) MHz, respectively. Least-squares fits of the bromine quadrupole hyperfine splittings gave χ values of 656.8 (88) and 551 (10) MHz for the ground states of 79 BrCNO and 81 BrCNO, respectively. The observed vibrational satellite pattern arising from the BrCN bending mode indicates that the molecule exhibits extremely quasilinear behavior, roughly analogous to that of OCCCO.
