title: Infrared Diode Laser Spectrum of the nu(1) Fundamental Band of ClBO.
abstract: The nu(1) band of ClBO has been recorded using infrared diode laser spectroscopy. The molecule was produced by reacting oxygen atoms, produced in a microwave discharge containing an O(2)/He mixture, with BCl(3). Thirty-three lines of the (35)Cl(11)B(16)O isotopomer and 32 lines due to the (37)Cl(11)B(16)O isotopomer have been assigned. By fixing the ground state constants to those previously obtained by microwave spectroscopy, a least-squares fit (rms = 0.0008) gave the following upper state constants; (35)Cl(11)B(16)O: nu(0) = 1972.18024(21) cm(-1), B(1) = 0.1725055(12) cm(-1); (37)Cl(11)B(16)O: nu(0) = 1971.82846(24) cm(-1), B(1) = 0.1688402(13) cm(-1). The rotational constants of all the fundamental bands of ClBO have been used to calculate an r(e) structure yielding r(e(B-Cl)) = 167.668(26) pm and r(e(B-O)) = 121.308(26) pm.
