In this paper, we study (n+1)-dimensional real submanifolds
M with (n 1)-contact CR dimension. On these manifolds there ex-
ists an almost contact structure F which is naturally induced from the
ambient space. Also, we study the condition h(FX; Y ) h(X; FY ) =
g(FX; Y )'; ' 2 TM?; on the almost contact structure F and on the
second fundamental form h of these submanifolds and we characterize
certain model spaces in contact odd-dimensional unit sphere.
