Combined Infrared and Analytical Electron Microscope Studies of Interplanetary Dust Particles

Bradley, J. P.; Humecki, H. J.; Germani, M. S.

Ultramicrotomed thin sections (less than 100 nm thick) of eight chondritic interplanetary dust particles (IDPs) were studied by analytical electron microscopy and IR microspectroscopy with the objective of identifying IDPs or their specific components with IR spectral transmission characteristics at 10 microns similar to those of comets. Two IDPs …
