| Abstract: | C6H5 + fragment ion produced from toluene,n-propylbenzene and acetophenone have been studied using an electron impact technique. The ionization efficiency data have been treated by the inverse convolution first differential technique. First and higher appearance energies for ions produced from the three precursors are reported. The heats of formation for the ions obtained at threshold from the three molecules are calculated |
