Well, whatever. I'll just assume that the OP knows something about the
RNA he has. But consider it could be:

1) prokaryotic or viral origin
2) mRNA that was chemically decapped or partially degraded
3) he could be looking for degradation intermediates.

If you want to get nitpicky I suppose you can call 2) or 3) "mRNA-
derived RNA fragments" or something, if that will make you happy.
