Toluenium ions [CH3C6H6]+, formed by protonation of toluene by C2H5+ ions in the cell of a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer, have been assayed by IR multiphoton dissociation (IRMPD) spectroscopy. Their IRMPD spectrum compares well with the calculated IR ...

The authors reported the appearance of a weak bond at 1657 cm− 1 in the FTIR spectrum of the grafted wood flour, owing to the attached unsaturation of the anhydride. This band substantially decreased after reaction with styrene, and weak absorption peaks appeared at 700–760 cm− 1 owing...
