Abstract

The donor-acceptor complexes (CH₃)₃N-BF₃ and (CH₃)₃N-B(CH₃)₃ have been reinvestigated at high resolution by rotational spectroscopy in a supersonic jet. Nuclear hyperfine structure resulting from both nitrogen and boron has been resolved and quadrupole coupling constants have been obtained. The results for both complexes indicate that approximately 0.4 electrons are transferred away from the (CH₃)₃N moiety upon formation of the dative bond.
