Detecting organic compounds in interstellar dust

[Prez Cannady]

Two questions:

1. What tools and techniques are typically used to determine and plot spatial distributions of compounds--particularly organic ones--in interstellar dust?
2. Is it presently possible to determine distributions of compounds along arcs distant from the galactic center? If so, can anyone point me to research along those lines or offer some hints on how to better refine my search?

"Interstellar dust"+"organic" yields 55k hits; you've gone through them all?

No. I have not sifted through 55,000 results. Or 102,000 for that measure.
