In this paper we study the problem of explicit representation and conver-gence of P ′al type (0;1) interpolation and its converse, with some additional conditions, on the non-uniformly distributed nodes on the unit circle obtained by projecting the interlaced zeros of Pn(x) and P′n(x) on the unit circle. The motivation to this problem can be traced to the recent studies on the regularity of Birkhoff interpolation and P ′al type interpolations on non-uniformly distributed zeros on the unit circle.
