Abstract

The structure of the weakly bound complex HCl BF₃ has been determined by molecular beam electric resonance spectroscopy. The molecule is a near prolate symmetric top with the chlorine atom 3.17 Å above the boron atom, on or very near the BF₃ threefold axis. The B-Cl-H angle is close to 90°. The spectroscopic constants for the H³⁵Cl ¹¹BF₃ isotope are (B+C)/2=1774.117(4) MHz, D _J=5.6(5) kHz, eqQ_a (³⁵Cl)=+25.761(8) MHz, eqQ^a (¹¹B)=+2.672(25) MHz, and μ_a=0.484(5)D.
