Abstract
More than 4500 lines of the v(2) + v(4) and v(4) +/- v(5) bands, linke d by a strong x-y Coriolis resonance, have been assigned, but only the perpendicular component of v(4) + v(5) was strong enough to be observ ed. A least squares fit over 4180 lines. according to a model taking a lso into account the 1(2,2) resonance inside the v(4) mode and two loc al resonances (an anharmonic one between v(4)(1) + v(5)(1) and 2v(2) 2v(6)(2), and a Coriolis one between v(2) + v(4)(-1) and v(1) + v(2)) , gave a r.m.s. deviation of 0.029 cm(-1). Explanations of several oth er local perturbations have been attempted.
