In this paper, we describe new high-resolution measurements of the absorption spectrum of (NH3)-N-14 in the 6850-7000 cm(-1) region using cavity-enhanced absorption spectroscopy (CEAS), and Fourier-transform spectroscopy (FTS) between similar to 6400 and 6900 cm(-1). The CEAS measurements were used to determine line positions, line intensities (cross-sections) and pressure-broadening parameters, the latter in three different bath gases. A total of 1117 NH3 lines were observed. The accuracy of the line positions is about 0.001 cm(-1), and absorptions cross-sections as low as 1 x 10(-23) cm(2) molecule(-1) are reported.
