We study how rotation affects observable amplitudes of high-order g- andmixed r/g-modes and examine prospects for their detection and identification.Our formalism, which is described in some detail, relies on a nonadiabaticgeneralization of the traditional approximation. Numerical results arepresented for a number of unstable modes in a model of SPB star, at rotationrates up to 250 km/s. It is shown that rotation has a large effect on modevisibility in light and in mean radial velocity variations. In most cases, fastrotation impairs mode detectability of g-modes in light variation, as Townsend(2003b) has already noted, but it helps detection in radial velocity variation.The mixed modes, which exist only at sufficiently fast rotation, are also moreeasily seen in radial velocity. The amplitude ratios and phase differences arestrongly dependent on the aspect, the rotational velocity and on the mode. Thelatter dependence is essential for mode identification.
