On what content sites are my ads displayed?

Is there a way to find out?

We are offering software products at a rather high price tag, which means we like to limit our ads to websites targeted at professionals. Showing our ads on content sites in Google's network increased the number of visitors, but the number of purchases stayed about the same.

Now we would like to know where the ads are actually displayed. There does not seem to be a way to get detailed information about content sites in the control panel, and our weblogs only tells us that most visitors come through "http://pagead2.googlesyndication.com/pagead/ads", which is not very helpful.

So does anybody know how I can get information about sites displaying our ads?
