Abstract HeI photoelectron spectra in the vapour phase and X-ray photoelectron spectra in the solid phase of the addition compounds of trimethylamine (TMA) with boron trihalides (BX 3; X= F, Cl, Br) are reported, and interpreted with the aid of ab initio SCF MO calculations. The shift in the binding energy of the amine lone-pair orbital n N correlates well with the calculated net charge transferred and structural changes upon complexation. The results ...
