Mass spectrometric study of aromatic derivatives of cycloalkanes and cycloalkanols

October 1, 1979
Author(s)
Anzor I. Mikaia, Vladimir G. Zaikin, Evgenyi Finkelstein, Valentin Vdovin
General and specific fragmentation pathways of arylcyclanes with three, four, five and six membered saturated rings under electron ionization are determined. The resulting characteristic ions are useful for structure elucidation. The measured appearance
