We present calculations that show many laser-coolable molecules have convenient rotational transitions that are exceptionally insensitive to magnetic fields. We verify this experimentally for CaF where we find a transition with sensitivity below 5 Hz G$^{-1}$ and use it to demonstrate a rotational coherence time of 6.4(8) ms in a magnetic trap. Simulations suggest it is feasible to extend this to more than 1 s using a smaller cloud ","authors_text":"B. E. Sauer, H. J. Williams, J. Aldegunde, Jeremy M. Hutson, L. Caldwell, M. R. Tarbutt, N.
