## Abstract The characteristic fragment of trimethylsilylated pantothenic acid (TMSโPA) at __m__/__z__ 291 upon electron ionization was shown to originate from the molecular ion by a McLafferty rearrangement instead of by ejection of 1,1,3,3โtetramethylโ1,3โdisilacyclobutane. The verification consi
## Abstract The mass spectrometric behavior of the diโTMSi derivatives of diaminoโ,dihydroxyโand aminohydroxynaphthalenes is described. The presence or lack of doublyโcharged ions in the mass spectra is correlated with substituent position. Comparison is made with the spectra of the disubstituted b
