Mass spectra of isotopic trimethylboranes

Mass spectra of isotopically normal, 10B-enriched, and deuterated trimethylboranes are analysed. In the isotopically normal compound an effective 10B/ 11B abundance ratio of 0·242 is calculated for the principal range, while 0·265 and 0·259 must be used for the low mass ranges of B(CH 3) 3 and B(CD...

Summary:Mass spectra of isotopically normal, 10B-enriched, and deuterated trimethylboranes are analysed. In the isotopically normal compound an effective 10B/ 11B abundance ratio of 0·242 is calculated for the principal range, while 0·265 and 0·259 must be used for the low mass ranges of B(CH 3) 3 and B(CD 3) 3, respectively. Explanations are offered to account for the significant differences observed among the three monoisotopic fragmentation patterns.
