The FBO molecule was generated by a dc discharge in a mixture of BF3, O2, and He and its vibration–rotation and rotation spectra were observed by using infrared diode laser spectroscopy and microwave spectroscopy, respectively. The ν1 B–O stretching mode of F1 1BO and F1 0BO and the ν1+ ν2− ν2 hot band of F1 1BO were observed in the region 2050 to 2140 cm− 1. Subsequently, the pure rotational spectrum was observed for the following ...
