FIG. 1.

Integrated TOF spectra of adenine (top panel) and cytosine (bottom panel) over the scan energy range. The DNA basis were vaporized using in-vacuum temperature-controlled oven vaporization (red line and left y-axis) and aerosol thermal desorption (black line and right y-axis). The intense peak at 28 amu in the aerosol spectrum corresponds to the N2 used as carrier gas. Other differences between the spectra are due to impurities in the oven.

FIG. 2.

TPEPICO spectra of the adenine parent obtained with 40 meV threshold electron resolution. The black curve is when adenine is vaporized with the aerosol source and the red curve is for in-vacuum oven. The inset presents an energy close up of the threshold region.

FIG. 3.

TPEPICO spectra of the cytosine parent obtained with 40 meV threshold electron resolution when using the aerosol source (black curve) and with 80 meV (red curve) when using the in-vacuum oven. The inset is an enlargement for the threshold ionization energy where the oblique lines are to enlighten the slopes at the ionization threshold. See text.
