The High-Resolution FTIR Spectrum and Equilibrium Structure of Chloro(sulphido)boron.
The FTIR spectrum of chloro(sulphido)boron, Cl-B&bond;S, has been recorded at 0.0035 cm(-1) resolution. The nu(3) bands of the isotopomers (35)Cl(11)B(32)S, (37)Cl(11)B(32)S, (35)Cl(11)B(34)S, (37)Cl(11)B(34)S, (35)Cl(10)B(32)S, (37)Cl(10)B(32)S, and (35)Cl(10)B(34)S have been analyzed to yield effective rotational and centrifugal distortion constants for the ground and a number of excited vibrational states. For the (35)Cl(11)B(32)S isotopomer the nu(1) band has also been analyzed. The rotational constants have been used to determine equilibrium bond lengths of 168.42(8) and 160.14(8) pm for the Cl-B and B-S bonds, respectively. Copyright 2000 Academic Press.
