Lett. 2024 Vol. 12, No. 1, 26 – 30 Web1.21.5.4 Mass Spectra. Mass spectral data have frequently been used in the structural determination of boron heterocycles. One paper has been devoted to the mass spectra of some six-membered boron–nitrogen systems. It was concluded that the spectra could be interpreted analogously to their hydrocarbon counterparts.

WebThe 13 C isotope is, of course, heavier than 12 C by 1 mass unit. In addition, about 0.015% of all hydrogen atoms are actually deuterium, the 2 H isotope. So the M+1 peak represents those few acetone molecules in the sample which contained either a 13 C or 2 H. Molecules with lots of oxygen atoms sometimes show a small M+2 peak (2 m/z units ...
WebAn interpretation of hydroboron mass spectra is complicated by the fact that boron has two isotopes of masses 10 and 11 in the relative amounts 0.20 and 0.80. Consequently, in poly atomic ions many different combinations of boron isotopes and hydrogen atoms contribute to the spectrum.
