ABSTRACT:
Seventeen stratospherically collected particles-8 of which are classified
as interplanetary dust particles (IDPs), 7 of which are classified as
probable terrestrial contaminants, and 2 of which have uncertain
origins-were studied with a microprobe 2-step laser mass spectrometer.
Many polycyclic arom. hydrocarbons (PAHs) and their alkylated derivs.
were identified in 2 of the 8 IDPs.  The PAHs obsd. include a high-mass
envelope not found in meteorites or terrestrial contaminants and
prominent odd-mass peaks suggestive of nitrogen-contg. functional groups
attached to arom. chromophores.  In addn., the complexity of the IDP mass
spectra has no precedence in previous studies of meteorite samples or
their acid residues.  Extensive checks were performed to demonstrate that
the PAH signals are not caused by terrestrial contaminants.
