摘要：

Absorption spectra of rotationally cold ammonia ((NH3)-N-14) molecules have been recorded in the 6400-6630 cm(-1) region, using the cavity-enhanced absorption technique in combination with a slit-nozzle expansion. Two perpendicular rovibrational bands have been identified: the nu(1) + nu(3) band at 6609 cm(-1), and a 'new' band at 6557 cm(-1) which is tentatively assigned to a transition into the \l\ = 2 component of the nu(1) + 2 nu(4) state.
