Some claim that there are two independent mixing angles
(θ= 35.3°, -54.7°) between 3P1 and 1P1
states of heavy-light mesons in the heavy quark symmetric limit,
and others claim there is only one (θ= 35.3°).
We clarify the difference between these two and suggest which should be
adopted. General arguments on the mixing angle between 3LL and 1LL of
heavy-light mesons are given in HQET and a general relation is derived in the
heavy quark symmetric limit as well as that including the
first-order correction in 1/mQ.
